Mammography and 99mTc-MIBI scintimammography in suspected breast cancer. (1/2964)

The aim of this work has been to evaluate whether a diagnostic protocol based on the joint use of mammography and 99mTc-methoxyisobutyl isonitrile (MIBI) scintimammography is capable of reducing the number of biopsies required in patients with suspected breast cancer. METHODS: We performed prone scintimammography in 90 patients with suspected breast cancer, involving 97 lesions. In all patients, the diagnosis was established by way of biopsy. On mammography, we evaluated the degree of suspicion of malignancy and the size of the lesion (smaller or larger than 1 cm in diameter). RESULTS: The results of only 41 of the biopsies indicated malignancy. On mammography, 20 lesions (of which 1 was breast cancer) were considered to be of low suspicion of malignancy, 31 (of which 4 were breast cancer) as indeterminate and 46 (of which 36 were breast cancer) as high. Fourteen lesions (2 low probability, 2 indeterminate and 10 high) were smaller than 1 cm, whereas 83 (18 low probability, 29 indeterminate and 36 high) were larger. The sensitivity, specificity, positive predictive value and negative predictive value of scintimammography were 85%, 79%, 74% and 88%, respectively. Scintimammography was positive in all cases of breast cancer that initially had a low or indeterminate suspicion of malignancy according to mammography, as well as in 30 cases of breast cancer that initially were highly suspicious. Six false-negative scintimammography studies were obtained in lesions with a high suspicion of malignancy. CONCLUSION: We propose a diagnostic protocol with a biopsy performed on lesions that have a high suspicion of malignancy as well as those with low or indeterminate suspicion that are smaller than 1 cm or with positive scintimammography results. This would have reduced the total number of biopsies performed by 34%. More importantly, there would have been a 65% reduction in number of biopsies performed in the low and indeterminate mammographic suspicion groups. All 41 cases of breast cancer would have been detected.  (+info)

The effect of the antiscatter grid on full-field digital mammography phantom images. (2/2964)

Computer Analysis of Mammography Phantom Images (CAMPI) is a method for making quantitative measurements of image quality. This article reports on a recent application of this method to a prototype full-field digital mammography (FFDM) machine. Images of a modified ACR phantom were acquired on the General Electric Diagnostic Molybdenum Rhodium (GE-DMR) FFDM machine at a number of x-ray techniques, both with and without the scatter reduction grid. The techniques were chosen so that one had sets of grid and non-grid images with matched doses (200 mrads) and matched gray-scale values (1500). A third set was acquired at constant 26 kVp and varying mAs for both grid conditions. Analyses of the images yielded signal-to-noise-ratio (SNR), contrast and noise corresponding to each target object, and a non-uniformity measure. The results showed that under conditions of equal gray-scale value the grid images were markedly superior, albeit at higher doses than the non-grid images. Under constant dose conditions, the non-grid images were slightly superior in SNR (7%) but markedly less uniform (60%). Overall, the grid images had substantially greater contrast and superior image uniformity. These conclusions applied to the whole kVp range studied for the Mo-Mo target filter combination and 4 cm of breast equivalent material of average composition. These results suggest that use of the non-grid technique in digital mammography with the GE-DMR-FFDM unit, is presently not warranted. With improved uniformity correction procedure, this conclusion would change and one should be able to realize a 14% reduction in patient dose at the same SNR by using a non-grid technique.  (+info)

Screening Mammography Program of British Columbia: pattern of use and health care system costs. (3/2964)

BACKGROUND: The use of mammography for screening asymptomatic women has increased dramatically in the past decade. This report describes the changes that have occurred in the use of bilateral mammography in British Columbia since the provincial breast cancer screening program began in 1988. METHODS: Using province-wide databases from both the breast cancer screening program and the provincial health insurance plan in BC, the authors determined the number and costs of bilateral mammography services for women aged 40 years or older between Apr. 1, 1986, and Mar. 31, 1997. Unilateral mammography was excluded because it is used for investigating symptomatic disease and screening abnormalities, and for follow-up of women who have undergone mastectomy for cancer. RESULTS: As the provincial breast cancer screening program expanded from 1 site in 1988 to 23 in 1997, it provided an increasing proportion of the bilateral mammographic examinations carried out each year in BC. In fiscal year 1996/97, 65% of bilateral mammographic examinations were performed through the screening program. The cost per examination within the screening program dropped as volume increased. Thirty percent more bilateral mammography examinations were done in 1996/97 than in 1991/92, but health care system expenditures for these services increased by only 4% during the same period. In calendar year 1996, 21% of new breast cancers were diagnosed as a result of a screening program visit. INTERPRETATION: Substantial increases in health care expenditures have been avoided by shifting bilateral mammography services to the provincial screening program, which has a lower cost per screening visit.  (+info)

Moderate physical activity in relation to mammographic patterns. (4/2964)

High-risk mammographic patterns may be used as a surrogate end point for breast cancer in etiologic research as well as in prevention studies. Physical activity may be one of the few modifiable risk factors for breast cancer. We examined the relationship between physical activity and mammographic patterns among 2720 Norwegian women, ages 40-56 years, who participated in both the Second and Third Tromso studies. Epidemiologic data were obtained through questionnaires. Two questions from the Second Tromso study and five questions from the Third elicited information on physical activity. The mammograms were categorized into five groups based on anatomical-mammographic correlations. For analysis, patterns I through III were combined into a low-risk group and patterns IV and V into a high-risk group. Odds ratios that were adjusted for age, education, menopausal status, body mass index, parity, age at menarche, oral contraceptive use, and alcohol intake, with 95% confidence intervals, were estimated using logistic regression. Women who reported moderate physical activity, i.e., more than 2 h/week, were 20% less likely (odds ratio, 0.8; 95% confidence interval, 0.6-1.1) to have high-risk mammographic patterns compared with those who reported being inactive. This relationship remains consistent when stratified by menopausal status, parity, and tertiles of body mass index. However, all of the associations between various measures of physical activity and high-risk patterns found in this study are weak with confidence intervals that include 1.0. Thus, chance is a reasonable explanation for the weak associations found. The relationship between physical activity and high-risk patterns should be examined further as a means to explore the biologic mechanisms relating physical activity to breast cancer risk.  (+info)

Macronutrient intake and change in mammographic density at menopause: results from a randomized trial. (5/2964)

To examine the effects of dietary fat intake on breast cancer risk, we are conducting a randomized trial of dietary intervention in women with extensive areas of radiologically dense breast tissue on mammography, a risk factor for breast cancer. Early results show that after 2 years on a low-fat, high-carbohydrate diet there is a significant reduction in area of density, particularly in women going through menopause. In women who went through menopause during the 2-year follow-up, the mean decreases in area of density and percentage of density in the intervention group were 11.0 cm2 and 11.0%, respectively, whereas the control group decreased 4.5 cm2 and 5.2%. The purpose of this analysis was to determine whether changes in intake of specific macronutrients could account for the observed reduction in breast density in these women. Differences between 2-year and baseline values of macronutrients (averaged over 3 nonconsecutive days of food intake) were calculated. We examined the effect of dietary variables, adjusted for changes in total calorie intake and weight and for family history of breast cancer, on changes in area of density and percentage of density using linear regression. Reduction in total or saturated fat intake or cholesterol intake was significantly associated with decreased dense area (p < or = .004). The most significant dietary variable associated with reduction in percentage of density was reduction in dietary cholesterol intake (P = 0.001), although reducing saturated fat intake was of borderline significance (P = 0.05). The effect of the membership in the intervention and control groups on change in area of density or percentage of density was reduced by models that included changes in intake of any fat, or cholesterol, or carbohydrates. The observation of an effect of diet at menopause on breast density, a marker of increased risk of breast cancer, may be an indication that exposures at this time have an enhanced effect on subsequent risk.  (+info)

'Should a mammographic screening programme carry the warning: screening can damage your health!'? (6/2964)

The balanced presentation afforded by convening a Citizens' Jury when considering a major question such as the introduction of a breast screening programme is advocated. This method would enable account to be taken of all the costs, both human and financial, to all those affected, both participating and organizing, as well as the benefits. Provision of such a democratic opportunity enables consideration to be given to a broad range of factors, by selection of an appropriate range of witnesses, with the advantage of involving the lay public in this decision-making process. Attendance by health correspondents, medical journalists and other media representatives enables publicization of a democracy in action whilst helping to inform the wider debate. Such an exercise could inform whether the NHS BSP should continue in its current form.  (+info)

American Society of Clinical Oncology 1998 update of recommended breast cancer surveillance guidelines. (7/2964)

OBJECTIVE: To determine an effective, evidence-based, postoperative surveillance strategy for the detection and treatment of recurrent breast cancer. Tests are recommended only if they have an impact on the outcomes specified by American Society of Clinical Oncology (ASCO) for clinical practice guidelines. POTENTIAL INTERVENTION: All tests described in the literature for postoperative monitoring were considered. In addition, the data were critically evaluated to determine the optimal frequency of monitoring. OUTCOME: Outcomes of interest include overall and disease-free survival, quality of life, toxicity reduction, and secondarily cost-effectiveness. EVIDENCE: A search was performed to determine all relevant articles published over the past 20 years on the efficacy of surveillance testing for breast cancer recurrence. These publications comprised both retrospective and prospective studies. VALUES: Levels of evidence and guideline grades were rated by a standard process. More weight was given to studies that tested a hypothesis directly relating testing to one of the primary outcomes in a randomized design. BENEFITS, HARMS, AND COSTS: The possible consequences of false-positive and -negative tests were considered in evaluating a preference for one of two tests providing similar information. Cost alone was not a determining factor. RECOMMENDATIONS: The attached guidelines and text summarize the updated recommendations of the ASCO breast cancer expert panel. Data are sufficient to recommend monthly breast self-examination, annual mammography of the preserved and contralateral breast, and a careful history and physical examination every 3 to 6 months for 3 years, then every 6 to 12 months for 2 years, then annually. Data are not sufficient to recommend routine bone scans, chest radiographs, hematologic blood counts, tumor markers (carcinoembryonic antigen, cancer antigen [CA] 15-5, and CA 27.29), liver ultrasonograms, or computed tomography scans. VALIDATION: The recommendations of the breast cancer expert panel were evaluated and supported by the ASCO Health Services Research Committee reviewers and the ASCO Board of Directors.  (+info)

Double-phase 99mTc-sestamibi scintimammography and trans-scan in diagnosing breast cancer. (8/2964)

The goal of our study was to assess the value of both scintimammography with 99mTc-sestamibi (SMM) and trans-scan (T-scan) in detecting breast cancer. METHODS: A total of 121 women were evaluated by palpation, mammography, SMM and T-scan. SMM was performed in the prone, breast dependent position. Immediate and delayed views (double-phase) were obtained. T-scan is a new breast imaging method that maps noninvasively the distribution of tissue electrical impedance and capacitance. RESULTS: SMM had 88.9% sensitivity, 88.4% specificity and 88.4% accuracy in detecting breast cancer. SMM had 100% sensitivity in detecting breast tumors >1 cm and only 66% sensitivity in detecting tumors <1 cm. T-scan had 72.2% sensitivity and 67% specificity in detecting breast cancer. It detected one more breast cancer than SMM, at the expense of 27 additional false-positive results. CONCLUSION: Double-phase SMM was sensitive and specific in detecting breast cancer. This method may reduce the rate of negative breast biopsies in tumors >1 cm. T-scan was only moderately accurate in detecting breast cancer. Its addition to SMM did not improve significantly the rate of breast cancer detection. However, because of its complete noninvasiveness, large-scale applicability and low cost, T-scan deserves further refining.  (+info)

If screened regularly, over one-half of U.S. women will have abnormal mammography results that require additional follow-up but in which cancer is not detected (false-positive result). This dissertation presents and tests a model, informed by theoretical and empirical evidence, of the relationship between receipt of false-positive mammography results and adherence to subsequent mammography screening. To test study hypotheses, I analyzed longitudinal data (n=2406), gathered through medical claims records and telephone interviews, as part of the PRISM (Personally Relevant Information on Screening Mammography) intervention trial to increase repeat mammography adherence among insured North Carolina women. About 8% of women received false-positive mammography results within 14 months of their interviews. Among women who said their physicians had not advised them to get mammograms in the past year, those who received false-positive results were more likely to have no subsequent mammogram on record ...
This prospective national multicenter multivendor trial aims at determining the impact of the novel technique Digital Breast Tomosynthesis (DBT) in the assessment and screening for breast cancer. Mammography is the primary imaging modality for the early detection of clinically occult breast cancer.. Despite advances in mammographic technique, mammography is still limited with regard to both sensitivity and specificity. In the majority of cases these limitations arise from the masking of subtle breast cancer lesions by overlapping breast tissue.. DBT is a novel technique that tries to overcome these limitations by performing a 3D-reconstruction of breast tissue from multiple low-dose digital mammographic images acquired in several planes in a 15 to 50 degree angle.. Early studies indicate an advantage of DBT compared to the standard Full Field Digital Mammography (FFDM) in terms of an improvement of specificity without cutback in sensitivity.. Controversy continues over the use of DBT in ...

Screening 3D Mammography can assist your physician in the detection of disease even if you have no complaints or symptoms. Initial mammographic images themselves are not always enough to determine the existence of benign or malignant disease with certainty. If a finding or spot seems suspicious, our radiologist may recommend further diagnostic studies. Diagnostic Mammography is used to evaluate a patient with abnormal clinical findings, such as a breast lump, pain or a history of breast cancer. Diagnostic 3D Mammography may also be done after an abnormal screening mammography in order to determine the cause of the area of concern on the screening exam. Not all cancers of the breast can be seen on mammography. Interpretations of mammograms can be difficult because a normal breast can appear differently for each woman. With the assistance of our CADX system, a computer-aided detection system, the radiologist gets a second look at your mammogram. It is a routine part of the mammography reading ...

Mammography is effective in the early detection of breast cancer, especially among women 50 years and older. Detection and treatment of breast cancer at an early stage of disease can improve survival and yield substantial savings in medical care costs. This manual is a source of basic information on mammography and the intervention strategies and tools that health plans may use to help increase the screening rates. The manual is designed to be user-friendly, practical and adaptable to the needs and capacity of different health plans and will assist health plans to: 1. assess existing barriers to mammography; 2. identify the characteristics of members, providers and health care delivery systems for use in tailoring intervention strategies to increase their effectiveness; 3. identify the population(s) and providers(s) to target for intervention as well as the missed and untapped opportunities to increase mammography rates; 4. select and implement appropriate intervention strategies including those ...
Mammography is currently the only documented effective imaging tool for breast cancer screening. However, the sensitivity of mammography may be reduced in dense breasts, and sometimes it is difficult to even perceive a very subtle cancer which presents as a small stellate lesion, or very faint microcalcifications, missed diagnosed thus occurs. Herein, some researchers in Western countries developed computer-aided detection (CAD) system to help radiologists detect subtle, easily overlooked findings to facilitate early breast cancer detection, and most of the research regarding CAD was used in screen-film mammography (SFM) system. Ikeda, et al, worked on the retrospective CAD usage of those negative mammograms which later developed breast cancers. CAD could correctly mark 40% of the areas on these mammograms reported negative previously that later developed evident cancers. However, 80% of these are only nonspecific findings, and do not warrant recall for additional workup even at retrospective ...
This study is the first to comprehensively evaluate the cost-effectiveness of the combined use of mammography with CBE in breast cancer early detection while accounting for costs of screening, work-up, biopsies due to true or false-positive examinations, and treatments. We assessed current recommended guidelines from three major cancer organizations and compared them with other realistic strategies that combine mammography and CBE with different starting ages and intervals.. Compared with the alternatives, two of the recommended strategies are cost-effective in general: the NCI/USPSTF recommendation of annual mammography and CBE from ages 40 to 79 years, and the most effective but expensive recommendation from the ACS that begins CBE at age 20 years, followed by mammography and CBE from ages 40 to 79 years. The NCI/USPSTF recommendation of annual mammography alone from ages 40 to 79 years is cost-effective when the sensitivity of CBE is low, according to community-based settings. The NCI/USPSTF ...
What is breast tomosynthesis?. Tomosynthesis, the latest in digital mammography, is a form of 3D mammography that works by using 3D technology to capture multiple images of the breast from different angles. Unlike conventional mammography, which produces a flat image, tomosynthesis produces a more detailed, multi-layered image of the breast tissue.. How tomosynthesis can help you. This 3D technology gives out dedicated womens radiologists the clearest and most detailed images for the fastest, most accurate results. This is especially important for women with dense breast tissue -- something only detected with a mammogram.. Tomosynthesis detects cancer up to 15 months earlier than traditional mammograms, reduces the risk of false positives and detects 41 percent more invasive breast cancers.*. Early detection saves lives. Schedule your 3D mammogram today. Gwinnett Medical Center Imaging has three convenient Atlanta-area locations in Lawrenceville, Duluth, and Hamilton Mill.

Interval cancers are tumors arising after a negative screening episode and before the next screening invitation. They can be classified into true interval cancers, false-negatives, minimal-sign cancers, and occult tumors based on mammographic findings in screening and diagnostic mammograms. This study aimed to describe tumor-related characteristics and the association of breast density and tumor phenotype within four interval cancer categories. We included 2,245 invasive tumors (1,297 screening-detected and 948 interval cancers) diagnosed from 2000 to 2009 among 645,764 women aged 45 to 69 who underwent biennial screening in Spain. Interval cancers were classified by a semi-informed retrospective review into true interval cancers (n = 455), false-negatives (n = 224), minimal-sign (n = 166), and occult tumors (n = 103). Breast density was evaluated using Boyds scale and was conflated into: |25%; 25 to 50%; 50 to 75%; |75%. Tumor-related information was obtained from cancer registries and clinical

We used ...
There are strong empirical data suggesting that increased mammographic density is associated with breast cancer risk. Byrne et al. (14) studied a group of 1880 women from the Breast Cancer Detection Demonstration Project and found that dense breasts on mammography were associated with increased risk of breast cancer independent of family history, age at first birth, alcohol consumption, and history of prior biopsy. They also found that the higher relative risk for these patients was present for both premenopausal and postmenopausal women, and it persisted for 10 or more years. Byng et al. (6) estimate that because higher breast density is more common, it may confer a higher attributable risk of breast cancer than other factors, such as the BRCA 1 or BRCA 2 gene. A meta-analysis published by Warner et al. (15) found that the ORs for the risk of increased mammographic density varied according to study design and the method used to classify mammographic pattern; quantitative classification methods ...

Mammography (also called mastography) is the process of using low-energy X-rays (usually around 30 kVp) to examine the human breast for diagnosis and screening. The goal of mammography is the early detection of breast cancer, typically through detection of characteristic masses or microcalcifications. Like all X-rays, mammograms use doses of ionizing radiation to create images. These images are then analyzed for any abnormal findings. It is normal to use lower-energy X-rays, typically Mo (K-shell x-ray energies of 17.5 and 19.6 keV) and Rh (20.2 and 22.7 keV) than those used for radiography of bones. Ultrasound, ductography, positron emission mammography (PEM), and magnetic resonance imaging (MRI) are adjuncts to mammography. Ultrasound is typically used for further evaluation of masses found on mammography or palpable masses not seen on mammograms. Ductograms are still used in some institutions for evaluation of bloody nipple discharge when the mammogram is non-diagnostic. MRI can be useful for ...
We examined the relationship between breast cancer family history and mammographic breast density. Participants included 35,019 postmenopausal women aged ≥40 years enrolled in a population-based mammo
HealthDay Reporter. MONDAY, Dec. 28, 2015 (HealthDay News) -- Ultrasound and mammography appear equally likely to detect breast cancer, a new study says.. The finding is good news, particularly for women who live in developing countries that typically have more access to ultrasound than to mammography, the researchers said.. While the detection rate with ultrasound was comparable to that of mammography, it looks like ultrasound does better than mammography for node-negative invasive cancer, said study leader Dr. Wendie Berg, professor of radiology at Magee-Womens Hospital of UPMC in Pittsburgh. Node-negative invasive cancer is cancer that hasnt invaded the lymph nodes, but has grown past the initial tumor, according to the U.S. National Cancer Institute.. The downside [to ultrasound] is, there were more false positives, Berg said.. At least one expert doesnt expect this study to change current screening practice in the United States.. For U.S. patients, what [this study] really confirms ...
Summary of H.R.1132 - 110th Congress (2007-2008): National Breast and Cervical Cancer Early Detection Program Reauthorization Act of 2007
In the last 10 years, the Breast Cancer Surveillance Consortium (BCSC) has released numerous studies that show computer-aided detection (CAD) for screening mammography can lead to decreased radiologist reading accuracy. According to a recent study published by the Journal of the American College of Radiology, however, CAD use at digital screening mammography facilities remained stable from 2008 to 2016.
This study retrospectively analyzed the mean glandular dose (MGD) to 133 breasts from 132 subjects, all women, who participated in a clinical trial evaluating dedicated breast CT in a diagnostic population. The clinical trial was conducted in adherence to a protocol approved by institutional review boards and the study participants provided written informed consent. Individual estimates of MGD to each breast from dedicated breast CT was obtained by combining x-ray beam characteristics with estimates of breast dimensions and fibroglandular fraction from volumetric breast CT images, and using normalized glandular dose coefficients. For each study participant and for the breast corresponding to that imaged with breast CT, an estimate of the MGD from diagnostic mammography (including supplemental views) was obtained from the DICOM image headers for comparison. This estimate uses normalized glandular dose coefficients corresponding to a breast with 50% fibroglandular weight fraction. The median

Under license from MGH, GE Healthcare will make a new three dimensional digital mammography service available to women after FDA approval. This technology was developed here at the MGH under the leadership of Daniel Kopans, MD.
CHICAGO, Nov. 27, 2012 /PRNewswire-USNewswire/ -- The radiation dose to areas of the body near the breast during mammography is negligible, or very low, and does not result in an increased risk of cancer, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). The results suggest that the use of thyroid shields during mammography is unnecessary.. Thyroid shields can impede good mammographic quality and, therefore, are not recommended during mammography, said Alison L. Chetlen, D.O., assistant professor of radiology at Penn State Hershey Medical Center.. During mammography, some X-rays scatter away from the primary beam in the breast and spread outward in different directions. Although this scatter radiation is much weaker than the primary beam, there has been concern that women exposed to it during mammography could face an increased risk of cancer, especially in radiosensitive areas like the thyroid gland.. To better understand the ...
Women who undergo routine mammograms at the Marlborough Hospital Womens Imaging Center at 28 Newton St. in Southboro now have the latest screening and diagnostic technology available to them. The center is one of the first womens centers in the United States to offer breast cancer screening with a Selenia Dimensions digital mammography system, the latest generation of mammography equipment from Hologic, a womens healthcare company that is the world leader in breast cancer diagnosis and
All analysis was based on digitized film mammograms. Analysis was based on the last pre-diagnostic mammographic image per woman, using the mediolateral oblique view of the breast contralateral to the future tumor. To avoid image acquisition bias related to suspected or diagnosed cancer we did not consider mammograms that were acquired later than 30 days before diagnosis. PD values were calculated by an automated ImageJ-based method developed and validated by Li et al. in 2012 [18]. This method attempts to mimic the outcome of the gold standard area-based PD measurement method, Cumulus [19], and a high correlation (r = 0.884) between the two methods was demonstrated.. Our aim was to study features of the dense area in the mammograms, which were obtained by three processing steps: pre-processing of the image, dense area selection, and feature extraction. First, the images were pre-processed by automatically removing nametags and other artifacts, as well as reducing contrast intensity differences ...
DESCRIPTION (provided by applicant): Breast carcinoma is the leading cause of cancer in women in the U.S. It is well known that if breast cancer is detected when the tumor is small and axillary nodes are not involved, the survival rate is very high. However, if the cancer has spread with time, the survival rate drops significantly. Early detection of breast tumors is therefore critical to the successful treatment of breast cancer and significant reduction in the breast cancer mortality rate (30 to 50%) can be achieved through early detection of breast carcinoma by X-ray mammography. X-ray mammography is currently performed using a film-screen system and while it has shown good success in detecting early stage, clinically occult breast cancer the film-screen detector has limited latitude and dynamic range. Its performance is also affected by trade-off between detection efficiency and spatial resolution due to increased light spreading in thicker screens which are more efficient in stopping ...
Architectural distortion, the non-mass but potentially ominous clinical feature observed in many breast imaging procedures, is less likely to signal malignancy when its detected on screening mammography rather than diagnostic mammography or when it doesnt correlate with a subsequent targeted ultrasound exam.
Our study aimed to compare contrast-enhanced mammography with breast MRI in evaluating residual breast cancer in patients undergoing presurgical systemic treatment to shrink their tumour size, says Bhavika Patel, M.D., a radiologist at Mayo Clinics Arizona campus. We identified patients who had both contrast-enhanced digital mammography and MRI after treatment to shrink their tumours and before additional therapy or a mastectomy.. Dr. Patel and her colleagues conducted a retrospective review of contrast-enhanced digital mammography cases at Mayo Clinics Arizona campus between September 2014 and June 2016. Forty female patients met inclusion criteria. The mean age of study participants was 52.3 years. Thirty-four patients received chemotherapy, and six patients received endocrine therapy.. Researchers interpreted radiographic images in a blinded fashion and compared residual size on imaging to pathology from surgical samples. Their results indicated that both imaging modalities demonstrate ...
BACKGROUND The results of randomized trials show that breast cancer screening by mammography reduces breast cancer mortality by up to 40% in women aged 50-69 years. Because of these results, by 1998, 22 countries, including Canada, had established population-based organized screening programs. This paper presents the results of screening mammography in 1996 for 7 provincially organized breast cancer screening programs in Canada. METHODS Analyses of interim performance indicators for screening mammography have been calculated from data submitted to the Canadian Breast Cancer Screening database. The data set consisted of data from 7 provincial programs and was limited to mammographic screens for women aged 50-69 years (n = 203,303). Screening outcomes and performance indicators were calculated for abnormalities detected by screening mammography only. RESULTS The abnormal recall rate was 9.5% for first screens and 4.6% for subsequent screens, and the cancer detection rate per 1000 women screened was 6
Abstract Background: Screening mammography has lower sensitivity and specificity in women with dense breasts, who experience higher breast cancer risk. Purpose: To perform a systematic review of reproducibility of Breast Imaging Reporting and Data System (BI-RADS) density categorization and test performance and clinical outcomes of supplemental screening with breast ultrasonography, magnetic resonance imaging (MRI), and digital breast tomosynthesis (DBT) in women with dense breasts and negative mammography results. Data Sources: MEDLINE, PubMed, EMBASE, and Cochrane database from January 2000 to July 2015. Study Selection: Studies reporting BI-RADS density reproducibility or supplemental screening results for women with dense breasts. Data Extraction: Quality assessment and abstraction of 24 studies from 7 countries; 6 studies were good-quality. Data Synthesis: Three good-quality studies reported reproducibility of BI-RADS density; 13% to 19% of women were recategorized between ``dense`` and ...
Women at high risk for breast cancer, particularly women younger than 30, should weigh the benefits of screening mammography against the potential risks from low-dose radiation exposure. The American Cancer Society recommends annual screening with mammography and MRI for some high-risk women, typically beginning at age 30.

Y1 - 2002/7/8. N2 - Mammography dose increases with compressed breast thickness (CBT), but few studies have examined other correlates of dose. The purpose of this study was to evaluate the relation between factors such as race, age, body mass index (BMI), CBT, and menopausal status and mammography screening dose, measured for 509 women in a US population. A multiple linear regression model was developed for dose, based on consideration of these factors as well as examination characteristics. BMI and number of films during examination were positively related to dose. After adjusting for these factors, high CBT also leads to higher dose. Whites receive lower doses than black women but differences are slight after controlling for the effects of CBT and BMI, which were significantly higher among black women. ...
Both black and white women age 75 to 84 years who underwent annual mammography had lower 10-year breast cancer mortality than corresponding women who underwent biennial or no/irregular mammographies.

Moffitt Cancer Center Screening and Prevention, 4117 E. Fowler Ave., offers women more comprehensive breast imaging through 3D mammography and automated breast ultrasound (ABUS). Moffitt is the only hospital in Florida that uses the General Electric Invenia 3rd Generation ABUS technology to help physicians look at dense breast tissue. Three-dimensional breast and ABUS scans offer a better chance to diagnose breast cancer early, at a more treatable stage for women with dense breasts.. Breast tomosynthesis, or 3-D mammography, produces a three-dimensional view of the breast tissue that helps radiologists identify and characterize individual breast structures without the confusion of overlapping tissue. The screenings are quicker, produce sharper images and are more comfortable for patients.. Moffitts automated breast ultrasound technology will help to increase breast cancer detection for women with dense breast tissue with no previous clinical breast interventions. Using ABUS, radiologists can ...
We had conducted a survey on Mean Glandular Dose (MGD) from Full-Field Digital Mammography systems (FFDM) operate using Molybdenum/Molybdenum (Mo/Mo) and Tungsten/Rhodium (W/Rh) target/filter combinations. A survey was carried out at two randomly selected mammography centres in Malaysia, namely National Cancer Society and International Islamic University of Malaysia. The first centre operates using a W/Rh, while the second centre operates using an Mo/Mo target/filter combinations. On the basis of recorded information, data on mammographic views, MGD, age and Compressed Breast Thickness (CBT) were recorded for 100 patients, for each mammographic centre respectively. The MGD data were analyzed for variation with age group, with 5 years increment. The MGD data were also analyzed for variation with CBT, with 5 mm increment. We found that for both CC and MLO views, FFDM systems operated using Mo/Mo and W/Rh target/filter combinations present the same trend on MGD. The average MGD decreases as age ...

N2 - Background: Breast cancer is the most common malignant disease diagnosed in women worldwide. Screening with mammography has the ability to detect breast cancer at an early stage. The diagnostic accuracy of mammography screening largely depends on the radiographic density of the imaged breasts. In radiographically dense breasts, non-calcified breast cancers are more likely to be missed than in fatty breasts. As a consequence, some cancers are not detected by mammography screening. Supporters of adjunct ultrasonography to the screening regimen for breast cancer argue that it might be a safe and inexpensive approach to reduce the false negative ...
The long term objective is to develop x-ray systems that will minimize x-ray radiation dose to the patient during clinical diagnosis and routine screening, while maximizing the usefulness of data by applying advanced sensing and signal processing techniques. Near theoretical limit x-ray sensitivity can be achieved with advanced semiconductor detector arrays, so x-ray radiation dose can be reduced by more than an order of magnitude from that required by conventional screen-film systems. The inherently digital output of the detector array is ideally suited for Computed Radiology including electronic archiving and image transmission, image enhancement and analysis, and computer aided diagnosis. During Phase I, there are several specific aims: to produce a preliminary digital mammography system design to determine performance requirements for each of the subsystems; to design, fabricate, and test the critical detector arrays; to address the key detector packaging and system mechanical design issues; ...

N2 - A relatively large number of women in their 40s with high-density breasts, in which it can be difficult to detect lesions, are encountered in mammography cancer screenings in Japan. Here, we retrospectively investigated factors related to breast density. Two hundred women (40-49 years old) were examined at the screening center in our hospital. Multivariate analysis showed that factors such as small abdominal circumference, high HDL cholesterol, and no history of childbirth were related to high breast density in women in their 40s undergoing mammography. Other non-mammographic screening methods should be considered in ...

PURPOSE: To assess the formation, implementation, and operation of a community mammography registry, which is a consolidated database for all mammography and breast biopsy reports within a community. MATERIALS AND METHODS: A registry was created in Lee County, Fla. Mammography interpretation data were provided by 13 facilities and 38 radiologists organized in several private practice groups. RESULTS: The registry contains data on 87,926 mammograms and 3,234 breast biopsies performed between June 1991 and May 1994. The registry calculates individual and group mammography interpretation accuracy measures, such as sensitivity, specificity, positive predictive value, false-positive and false-negative rates, and clinical outcome measures such as sizes and stages of malignant lesions detected. CONCLUSION: The registry ...
Digital Breast tomosynthesis is also known as 3D Mammography which is more effective than a Digital Mammography screening. According to researchers, findings from Perelman School of Medicine DBT may help rein in cancer screening. In researchers study, they found 46483 screening incidents. According to Emily F.Conant MD, Chief of breast imaging at Penn Medicine Early detection is critical to saving lives and lowering costs. Digital Breast Tomosynthesis is more cost effective in terms of health systems. Nationwide DBT is increasingly accepted by radiologists . DBT is having a more effective screening method. According to researchers study they tested DM and DBT into four outcomes ie, True Positive (TP), True Negative (TN), False Positive (FP), False Negative (FN). By comparing DM episodes with DBT episodes, DBT episodes had lower False Positive and higher True Negative. With respect to True Positive and False Negative rates there were no important differences between DM and DBT ...
Mammography is currently the standard imaging modality used to screen women for breast abnormalities and, as a result, it is a tool of great importance for the early detection of breast cancer. Physical phantoms are commonly used as surrogates of breast tissue to evaluate some aspects of the performance of mammography systems. However, most phantoms do not reproduce the anatomic heterogeneity of real breasts. New fabrication technologies, such as 3D printing, have created the opportunity to build more complex, anatomically realistic breast phantoms that could potentially assist in the evaluation of mammography systems. The primary objective of this work is to present a simple, easily reproducible methodology to design and print 3D objects that replicate the attenuation profile observed in real 2D mammograms. The secondary objective is to evaluate the capabilities and limitations of the competing 3D printing technologies, and characterize the x-ray properties of the different materials they use. ...
When comparing downstream workup between the 3DT and 2DM groups, the researchers noted 18% compared with 29% underwent 6-month mammography (odds ratio [OR] = 1.83; P =.01) and 6% compared with 11% underwent breast MRI (OR = 1.90; P =.08). Ultrasound and biopsy occurred in 4% and 3%, respectively. When considering the downstream workup, the estimated cost per patient was $249 and $253.64 for the 3DT group and 2DM group, respectively.. The multivariable analysis revealed that use of 3DT and follow-up mammography at least 6 months after radiation treatment were independent predictors for reduced downstream workup.. Despite the fact that 3DT is known to be more expensive than 2DM, the researchers findings and analysis of downstream effect show that it is ultimately a more cost effective option.. Reference.

A method and system for detecting and displaying clustered microcalcifications in a digital mammogram, wherein a single digital mammogram is first automatically cropped to a breast area sub-image which is then processed by means of an optimized Difference of Gaussians filter to enhance the appearance of potential microcalcifications in the sub-image. The potential microcalcifications are thresholded clusters are detected, features are computed for the detected clusters, and the clusters are classified as either suspicious or not suspicious by means of a neural network. Thresholding is preferably by sloping local thresholding but may also be performed by global and dual-local thresholding. The locations in the original digital mammogram of the suspicious detected clustered microcalcifications are indicated. Parameters for use in the detection and thresholding portions of the system are computer-optimized by means of a genetic algorithm. The results of the system are optimally combined with a radiologist
Architectural distortion is an important ultrasonographic indicator of breast cancer. However, it is difficult for clinicians to determine whether a given lesion is malignant because such distortions can be subtle in ultrasonographic images. In this paper, we report on a study to develop a computerized scheme for the histological classification of masses with architectural distortions as a differential diagnosis aid. Our database consisted of 72 ultrasonographic images obtained from 47 patients whose masses had architectural distortions. This included 51 malignant (35 invasive and 16 non-invasive carcinomas) and 21 benign masses. In the proposed method, the location of the masses and the area occupied by them were first determined by an experienced clinician. Fourteen objective features concerning masses with architectural distortions were then extracted automatically by taking into account subjective features commonly used by experienced clinicians to describe such masses. The k-nearest neighbors (k-NN
The purpose of this randomized controlled trial was to determine the impact of a multicomponent intervention on mammography rates, including a practice facilitator and best practice methods. The results suggest that this intervention can improve mammography rates in a range of practice settings. Given the low mammography rates in the state of Oklahoma, having proven strategies that increase the number of women who choose mammography screening could potentially reduce the burden of breast cancer within the state through early detection, when treatment is more likely to be efficacious. These findings are consistent with other studies that have tested multicomponent interventions that included modified academic detailing, patient education, physician reminders, audit and feedback, prompt and reminder systems;28 physician education, and a practice facilitator to help redesign office routines including flow sheets; physician education, provider prompts, patient reminders, printed patient education ...
TY - JOUR. T1 - Supplementary screening sonography in mammographically dense breast. T2 - Pros and cons. AU - Youk, Ji Hyun. AU - Kim, Eun Kyung. PY - 2010/11/1. Y1 - 2010/11/1. N2 - Sonography is an attractive supplement to mammography in breast cancer screening because it is relatively inexpensive, requires no contrast-medium injection, is well tolerated by patients, and is widely available for equipment as compared with MRI. Sonography has been especially valuable for women with mammographically dense breast because it has consistently been able to detect a substantial number of cancers at an early stage. Despite these findings, breast sonography has known limitations as a screening tool; operator-dependence, the shortage of skilled operators, the inability to detect microcalcifications, and substantially higher false-positive rates than mammography. Further study of screening sonography is still ongoing and is expected to help establish the role of screening sonography.. AB - Sonography is ...
Breast tomosynthesis, or 3D mammography, is a technique using X-rays to produce a three dimensional picture of the breast and decrease false positive results.
Background:. Volatile organic compounds (VOCs) in breath have been reported as biomarkers of breast cancer and abnormal mammograms, apparently resulting from increased oxidative stress and cytochrome p450 induction. We evaluated a six-minute point-of-care breath VOC assay at three breast cancer screening centers in USA and the Netherlands.. Methods:. 244 women had a screening mammogram (93/37 normal/abnormal) or a breast biopsy (cancer/no cancer 35/79). A mobile point-of-care system collected and concentrated breath and air VOCs for analysis with gas chromatography and surface acoustic wave detection. Chromatograms were segmented into a time series of alveolar gradients (breath minus room air). Segmental alveolar gradients were ranked as candidate biomarkers by C-statistic value (area under curve [AUC] of receiver operating characteristic [ROC] curve). Multivariate predictive algorithms were constructed employing significant biomarkers identified with multiple Monte Carlo simulations and ...
A team of California-based breast imagers and breast cancer risk specialists have developed a website to help navigate the new challenges posed by breast density notification laws, according to a special report published online in the journal Radiology.. While mammography is considered the best single modality for population-based screening, its sensitivity is diminished by up to 20 percent in patients with dense breasts (breasts with a higher ratio of fibroglandular tissue to fat). This reduction in sensitivity is due for the most part to masking, a phenomenon in which surrounding dense breast tissue obscures a cancer on mammography.. In response, several states have adopted laws requiring patient and referring physician notification when the interpreting radiologist determines that the pattern of fibroglandular tissue on a patients mammogram is considered dense.. In California, mandatory reporting requirements took effect on April 1, 2013. The law requires that patients with dense breast ...
This paper describes two approaches for accomplishing interactive feature analysis by overcomplete multiresolution representations. We show quantitatively that transform coefficients, modified by an adaptive non-linear operator, can make more obvious unseen or barely seen features of mammography without requiring additional radiation. Our results are compared with traditional image enhancement techniques by measuring the local contrast of known mammographic features. We design a filter bank representing a steerable dyadic wavelet transform that can be used for multiresolution analysis along arbitrary orientations. Digital mammograms are enhanced by orientation analysis performed by a steerable dyadic wavelet transform. Arbitrary regions of interest (ROI) are enhanced by Deslauriers-Dubuc interpolation representations on an interval. We demonstrate that our methods can provide radiologists with an interactive capability to support localized processing of selected (suspicion) areas (lesions). Features
Obesity and high radiologic breast density independently increase breast cancer risk. We evaluated the effect of surgical weight loss on mammographic density (MD). Patients undergoing bariatric surgery and screening mammography (MG) were identified, data regarding demographics, comorbidities, calculated and genetic breast cancer risk was collected. Patients had a MG before and after surgery. Fellowship-trained breast radiologists assigned Breast Imaging Reporting and Data System density categories. Patients underwent sleeve gastrectomy (n = 56) or gastric bypass (n = 7), 78% had hypertension, 48% had diabetes. Four had deleterious BRCA mutations, four were calculated high risk. Mean weight loss = 28.7 kg. Mean initial BMI = 44.3 kg/m2 (range:33-77), final BMI = 33.6 kg/m2 (range:20-62;p | 0.01). Density was unchanged in 53, decreased in 1, increased in 9. Of these 9(14%), 5 changed from almost entirely fatty to scattered MD, and 4 changed from scattered MD to heterogeneously dense. Mean weight loss of
Women with a family history of breast cancer have an increased risk of the disease. However, since they tend to experience greater surveillance for the disease, their breast cancers may be detected at an earlier stage, thus making it difficult to assess reliably whether tumour characteristics vary by family history. Information on 9,731 Million Women Study participants with screen-detected breast cancer, diagnosed in 1996-2003, and 37,983 matched controls, who also attended routine screening but were not diagnosed with breast cancer, was used to estimate adjusted relative risks (RRs) of screen-detected breast cancer in women with a family history of the disease. Women with a family history of breast cancer had an increased risk of screen-detected breast cancer (RR 1.57; 95% CI:1.47-1.68) compared with those without such a family history. The RRs were 1.58 (1.46-1.71) and 1.55 (1.34-1.80) for invasive and in situ breast cancer; 1.63 (1.49-1.79) and 1.55 (1.32-1.83) for node-negative and node-positive
Introduction: The combination of direct magnification mammography and computed radiography provides an improvement in spatial resolution of storage phosphor-based digital systems. A clinical study comparing conventional and digital direct magnification mammograms was performed. Methods: 100 survey mammograms in 1.5- or 1.7-fold magnification and 50 4-fold spot magnification views were obtained with a prototype direct magnification mammography system and a storage phosphor-based digital system. An intraindividual comparison of these with previous conventional radiograms of the same patients was carried out. Results: The diagnostic value of digital survey mammograms using the direct magnification technique is comparable to that of conventional radiograms of the breast, especially with regard to the identification of microcalcifications and lesions and the clinical consequences. Spot magnification views performed with this combination of techniques allowed improvement in the evaluation of

To investigate whether quantitative radiomic features extracted from digital breast tomosynthesis (DBT) are associated with Ki-67 expression of breast cancer. This is a prospective ethically approved study of 70 women diagnosed with invasive breast cancer in 2018, including 40 low Ki-67 expression (Ki-67 proliferation index |14%) cases and 30 high Ki-67 expression (Ki-67 proliferation index ≥ 14%) cases. A set of 106 quantitative radiomic features, including morphological, grey/scale statistics, and texture features, were extracted from DBT images. After applying least absolute shrinkage and selection operator (LASSO) method to select the most predictive features set for the classifiers, low versus high Ki-67 expression was evaluated by the area under the curve (AUC) at receiver operating characteristic analysis. Correlation coefficient was calculated for the most significant features. A combination of five features yielded AUC of up to 0.698. The five most predictive features (sphericity,
Women recalled for further assessment of soft tissue abnormalities were recruited and received standard supplementary views (typically spot compression views) and two-view GE DBT. The added value of DBT in the assessment process was determined by analysing data collected prospectively by unblinded radiologists working up the cases.. Following anonymisation of cases, there was also a retrospective multireader review. The readers first read bilateral standard two-view digital mammography (DM) together with the supplementary mammographic views and gave a combined score for suspicion of malignancy on a five-point scale. The same readers then read bilateral standard two-view DM together with two-view DBT. Pathology data were obtained. Differences were assessed using ROC analysis. ...
Our radiologists believe Breast Tomosynthesis/DBT is a valuable tool to provide a definitive diagnosis and reduce patient recalls for additional evaluation. Breast Tomosynthesis produces a three dimensional view of the breast tissue, which helps the radiologists identify and characterize individual breast structures without the confusion of overlapping tissue.. While Breast Tomosynthesis can benefit all screening and diagnostic mammography patients, it is especially valuable for women receiving a baseline screening, those who have dense breast tissue, and women with a personal history of breast cancer.. The Breast Tomosynthesis screening experience is similar to a traditional 2D mammogram. During the exam, multiple low-dose images of the breast are acquired at different angles. These images are then used to produce a 3D image of the breast in a series of one-millimeter slices, enabling the radiologist to scroll through the images to view the layers of the breast.. Our radiologists recommend you ...
In this study including 41,102 women from a large screening-based cohort, we found no evidence of an overall effect of statin use on absolute dense volume. Statin users had a significantly lower percent dense volume, but this difference was mainly attributable to a larger non-dense volume in statin users. While a large number of studies have investigated the effect of statin use on breast cancer risk and prognosis [6-14], only few studies have examined the association with mammographic density. Our results are in line with a longitudinal study showing no effect of statins on change in area-based mammographic density [28]. No differential effects were observed by statin class or treatment duration [13, 29] but interaction analyses revealed potential effect modification by HRT with a larger absolute dense volume among statin users who also reported HRT use.. Mammographic density can be expressed in both absolute and relative terms. The preferred MD measure for breast cancer risk prediction is ...

GATINEAU, Que. †A former medical technician accused of performing unnecessary and inappropriate breast exams at military recruiting centres in Ontario took the stand in his own defence Friday, and denied the exams ever took place.. Retired petty officer James Wilks faces eight counts of breach of trust and one count of sexual assault in connection with complaints filed by six women in Thunder Bay, London and Windsor, Ont.. The women have accused him of having them strip from the waist up so he could visually examine their breasts during routine medical exams at the recruiting centres. One also accused Wilks of touching her breasts under the pretence of conducting a breast exam.. But Wilks, who said he had conducted more than 3,000 medical examinations on prospective recruits during his more than 25 years in uniform, said he never asked any of the women to remove their tops. He also said he never touched any of the womens breasts.. I did not conduct any breast exams … or visual exams, ...
In medicine, breast imaging is the representation or reproduction of a breasts form. There are various methods of breast imaging. Mammography is the process of using low-energy X-rays (usually around 30 kVp) to examine the human breast, which is used as a diagnostic and screening tool. The goal of mammography is the early detection of breast cancer, typically through detection of characteristic masses and/or microcalcifications. For the average woman, the U.S. Preventive Services Task Force recommended (2009) mammography every two years in women between the ages of 50 and 74. The American College of Radiology and American Cancer Society recommend yearly screening mammography starting at age 40. The Canadian Task Force on Preventive Health Care (2012) and the European Cancer Observatory (2011) recommends mammography every 2-3 years between 50 and 69. These task force reports point out that in addition to unnecessary surgery and anxiety, the risks of more frequent mammograms include a small but ...

Results The diagnostic accuracy was not significantly different between two modalities. The image quality was superior in 2DSM (p-value 0.0362). Conclusions 2DSM showed equivalent diagnostic accuracy and superior image quality to FFDM. Overall characterization of the lesion was better in 2DSM, and 2DSM showed superiority in evaluation of ...
A method and system for detecting and displaying clustered microcalcifications in a digital mammogram, wherein a single digital mammogram is first automatically cropped to a breast area sub-image which is then processed by means of an optimized Difference of Gaussians filter to enhance the appearance of potential microcalcifications in the sub-image. The potential microcalcifications are thresholded, clusters are detected, features are computed for the detected clusters, and the clusters are classified as either suspicious or not suspicious by means of a neural network. Thresholding is preferably by sloping local thresholding, but may also be performed by global and dual-local thresholding. The locations in the original digital mammogram of the suspicious detected clustered microcalcifications are indicated. Parameters for use in the detection and thresholding portions of the system are computer-optimized by means of a genetic algorithm. The results of the system are optimally combined with a
Given that the premise of the hypothesis in this study depended on bilateral breast symmetry, it would be preferable to analyze each patients symmetry utilizing more remote mammograms prior to the detectable cancer. Unfortunately we did not have that dataset in our current study, thus were unable to carry out the analysis. Overall, the assessment of symmetry in mammography is potentially limited by the fact that natural distortions between breasts are likely to occur during the course of breast compression routinely used in mammography. As such, symmetry measures can be confounded by the nature of the imaging procedure itself [26]. In our recently published results using 3D MRI in the study of breast density in 58 normal women, 47 pre-menopausal and 11 post-menopausal women [32], we found that bilateral breasts in women without cancer are highly symmetrical (r = 0.97 for breast volume, r = 0.97 for fibroglandular tissue volume, and r = 0.98 for PD). Another study using MRI showed small ...
