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
Ninety-two women with advanced, unilateral breast cancer were classified according to the Wolfe and Nottingham classifications of mammographic parenchymal pattern (MPP). Both classifications of MPP...

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 ...
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.

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. ...

Informed choice is of ethical and practical importance in mammography screening. To assess the level to which decisions regarding such screening are informed is thus imperative, but no specific instrument has been available to measure informed choice in the German mammography screening programme. The aims of this study were to develop the Informed Choice in Mammography Screening Questionnaire (IMQ) and to find first evidence for the factor structure, reliability and validity of its different components. The IMQ was sent to 17.349 women aged 50 in Westphalia-Lippe, Germany. The instrument has been developed after consideration of (1) the results of qualitative interviews on decision making in the mammography screening programme, (2) relevant literature on other informed choice instruments and (3) a qualitative study on influencing factors. The IMQ comprises 3 scales (attitude, norms, and barriers), 1 index (knowledge) and singular items covering intention to participate and sociodemographic variables. To

BACKGROUND: Use of preoperative breast magnetic resonance imaging (MRI) among women with a new breast cancer has increased over the past decade. MRI use is more frequent in younger women and those with lobular carcinoma, but associations with breast density and family history of breast cancer are unknown. MATERIALS AND METHODS: Data for 3075 women ages ,65 years with stage 0-III breast cancer who underwent breast conserving surgery or mastectomy from 2005 to 2010 in the Breast Cancer Surveillance Consortium were linked to administrative claims data to assess associations of preoperative MRI use with mammographic breast density and first-degree family history of breast cancer ...
Mammography also involves exposure to potentially carcinogenic ionising radiation. BreastScreen Aotearoa states that the radiation risk from mammograms is "extremely small".. The website of Womens Health Action acknowledges the cancer risk from ionising radiation:. According to the site:. "The radiation risk from modern mammography is extremely low. For a woman attending breast screening every two years from the age of 50 to 64, the possible risk of dying from a breast cancer caused by radiation is estimated to be one in 20,000. For a woman who starts annual mammography at the age of 40, then has it every two years from 50 to 64, there would be one radiation induced breast cancer death per 10,000 women.". http://www.womens-health.org.nz/index.php?page=breastscreen-aotearoa. However, according to Dr Samuel Epstein, mammography (as practised in the USA) entails substantial cancer risks:. "Radiation from routine mammography poses significant cumulative risks of initiating and promoting breast ...

Our practice uses digital mammography. Digital mammography allows the radiologist to alter the orientation, magnification, brightness and contrast to more accurately evaluate the breast. Computer-aided detection, or CAD, uses a digitized mammographic image to search for abnormal areas of density, mass, or calcification that may indicate the presence of cancer. The CAD system highlights these areas, alerting the radiologist to a possible abnormality ...
A screening mammogram is an X-ray of the breast used to detect breast changes in women who have no signs of breast cancer. It usually involves two X-rays of each breast. Using a mammogram, it is possible to detect a tumor that cannot be felt.. A diagnostic mammogram is an X-ray of the breast used to diagnose unusual breast changes, such as a lump, pain, nipple thickening or discharge, or a change in breast size or shape.. A diagnostic mammogram is also used to evaluate abnormalities detected on a screening mammogram. It is a basic medical tool and is appropriate in the workup of breast changes, regardless of a womans age.. Mammography has been used for about 30 years, and in the past 15 years technical advancements have greatly improved both the technique and results. Today, specialized equipment, used only for breast X-rays, produce studies that are high in quality but low in radiation dose.. Mammography may be used either for screening or to make a diagnosis. Women older than 25 years should ...
Criticisms of the Canadian National Breast Screening Study NBSS assert that reported findings more deaths in women aged 40-49 allocated to mammography versus no mammography and no difference in mortality between women who had mammography and physical examination versus physical examination alone for those aged 50-59 may be due to more women...
Purpose: To determine improvement in breast cancer detection by using supplemental three-dimensional (3D) automated breast (AB) ultrasonography (US) with screening mammography versus screening mammography alone in asymptomatic women with dense breasts.

PURPOSE: Dedicated breast CT prototypes used in clinical investigations utilize single circular source trajectory and cone-beam geometry with flat-panel detectors that do not satisfy data-sufficiency conditions and could lead to cone beam artifacts. Hence, this work investigated the glandular dose characteristics of a circle-plus-line trajectory that fulfills data-sufficiency conditions for image reconstruction in dedicated breast CT. METHODS: Monte Carlo-based computer simulations were performed using the GEANT4 toolkit and was validated with previously reported normalized glandular dose coefficients for one prototype breast CT system. Upon validation, Monte Carlo simulations were performed to determine the normalized glandular dose coefficients as a function of x-ray source position along the line scan. The source-to-axis of rotation distance and the source-to-detector distance were maintained constant at 65 and 100 cm, respectively, in all simulations. The ratio of the normalized glandular dose
We live in a headline driven world. The role of mammography for women is not immune to that influence. There will be many, many headlines on this topic, but too few folks will actually read the body of the article. And there is no telling how the body of any particular media article is going to portray the story, whether it be written to scare women or provide them with accurate information.. There is no way to tell how women are going to make up their minds to get screened or not get screened for breast cancer, but I can bet you there are going to be some who see the headlines and decide that mammography is not for them. Unfortunately, the researchers cant tell them whether or not they made the right decision for themselves as an individual. We just dont have the science to answer that question for any individual woman. So it comes down to basic facts: until science supplies us with the accurate answer, each woman has to make a decision regarding screening mammography. Hopefully that decision ...
