Computed radiography dual energy subtraction: performance evaluation when detecting low-contrast lung nodules in an anthropomorphic phantom. (1/1703)

A dedicated chest computed radiography (CR) system has an option of energy subtraction (ES) acquisition. Two imaging plates, rather than one, are separated by a copper filter to give a high-energy and low-energy image. This study compares the diagnostic accuracy of conventional computed radiography to that of ES obtained with two radiographic techniques. One soft tissue only image was obtained at the conventional CR technique (s = 254) and the second was obtained at twice the radiation exposure (s = 131) to reduce noise. An anthropomorphic phantom with superimposed low-contrast lung nodules was imaged 53 times for each radiographic technique. Fifteen images had no nodules; 38 images had a total of 90 nodules placed on the phantom. Three chest radiologists read the three sets of images in a receiver operating characteristic (ROC) study. Significant differences in Az were only found between (1) the higher exposure energy subtracted images and the conventional dose energy subtracted images (P = .095, 90% confidence), and (2) the conventional CR and the energy subtracted image obtained at the same technique (P = .024, 98% confidence). As a result of this study, energy subtracted images cannot be substituted for conventional CR images when detecting low-contrast nodules, even when twice the exposure is used to obtain them.  (+info)

Computerized analysis of abnormal asymmetry in digital chest radiographs: evaluation of potential utility. (2/1703)

The purpose of this study was to develop and test a computerized method for the fully automated analysis of abnormal asymmetry in digital posteroanterior (PA) chest radiographs. An automated lung segmentation method was used to identify the aerated lung regions in 600 chest radiographs. Minimal a priori lung morphology information was required for this gray-level thresholding-based segmentation. Consequently, segmentation was applicable to grossly abnormal cases. The relative areas of segmented right and left lung regions in each image were compared with the corresponding area distributions of normal images to determine the presence of abnormal asymmetry. Computerized diagnoses were compared with image ratings assigned by a radiologist. The ability of the automated method to distinguish normal from asymmetrically abnormal cases was evaluated by using receiver operating characteristic (ROC) analysis, which yielded an area under the ROC curve of 0.84. This automated method demonstrated promising performance in its ability to detect abnormal asymmetry in PA chest images. We believe this method could play a role in a picture archiving and communications (PACS) environment to immediately identify abnormal cases and to function as one component of a multifaceted computer-aided diagnostic scheme.  (+info)

A reliability study for evaluating information extraction from radiology reports. (3/1703)

GOAL: To assess the reliability of a reference standard for an information extraction task. SETTING: Twenty-four physician raters from two sites and two specialties judged whether clinical conditions were present based on reading chest radiograph reports. METHODS: Variance components, generalizability (reliability) coefficients, and the number of expert raters needed to generate a reliable reference standard were estimated. RESULTS: Per-rater reliability averaged across conditions was 0.80 (95% CI, 0.79-0.81). Reliability for the nine individual conditions varied from 0.67 to 0.97, with central line presence and pneumothorax the most reliable, and pleural effusion (excluding CHF) and pneumonia the least reliable. One to two raters were needed to achieve a reliability of 0.70, and six raters, on average, were required to achieve a reliability of 0.95. This was far more reliable than a previously published per-rater reliability of 0.19 for a more complex task. Differences between sites were attributable to changes to the condition definitions. CONCLUSION: In these evaluations, physician raters were able to judge very reliably the presence of clinical conditions based on text reports. Once the reliability of a specific rater is confirmed, it would be possible for that rater to create a reference standard reliable enough to assess aggregate measures on a system. Six raters would be needed to create a reference standard sufficient to assess a system on a case-by-case basis. These results should help evaluators design future information extraction studies for natural language processors and other knowledge-based systems.  (+info)

An approach to the problems of diagnosing and treating adult smear-negative pulmonary tuberculosis in high-HIV-prevalence settings in sub-Saharan Africa. (4/1703)

The overlap between the populations in sub-Saharan Africa infected with human immunodeficiency virus (HIV) and Mycobacterium tuberculosis has led to an upsurge in tuberculosis cases over the last 10 years. The relative increase in the proportion of notified sputum-smear-negative pulmonary tuberculosis (PTB) cases is greater than that of sputum-smear-positive PTB cases. This is a consequence of the following: the association between decreased host immunity and reduced sputum smear positivity; the difficulty in excluding other HIV-related diseases when making the diagnosis of smear-negative PTB; and an increase in false-negative sputum smears because of overstretched resources. This article examines problems in the diagnosis and treatment of smear-negative PTB in high-HIV-prevalence areas in sub-Saharan Africa. The main issues in diagnosis include: the criteria used to diagnose smear-negative PTB; the degree to which clinicians actually follow these criteria in practice; and the problem of how to exclude other respiratory diseases that can resemble, and be misdiagnosed as, smear-negative PTB. The most important aspect of the treatment of smear-negative PTB patients is abandoning 12-month "standard" treatment regimens in favour of short-course chemotherapy. Operational research is necessary to determine the most cost-effective approaches to the diagnosis and treatment of smear-negative PTB. Nevertheless, substantial improvement could be obtained by implementing the effective measures already available, such as improved adherence to diagnostic and treatment guidelines.  (+info)

Clinical manifestation and survival of patients with idiopathic bilateral atrial dilatation. (5/1703)

We studied the histories of eight patients who lacked clear evidence of cardiac abnormalities other than marked bilateral atrial dilatation and atrial fibrillation, which have rarely been discussed in the literature. From the time of their first visit to our hospital, the patients' chest radiographs and electrocardiograms showed markedly enlarged cardiac silhouettes and atrial fibrillation, respectively. Each patient's echocardiogram showed a marked bilateral atrial dilatation with almost normal wall motion of both ventricles. In one patient, inflammatory change was demonstrated by cardiac catheterization and endomyocardial biopsy from the right ventricle. Seven of our eight cases were elderly women. Over a long period after the diagnosis of cardiomegaly or arrhythmia, diuretics or digitalis offered good results in the treatment of edema and congestion in these patients. In view of the clinical courses included in the present study, we conclude that this disorder has a good prognosis.  (+info)

Concurrent infection with Legionella pneumophila and Pneumocystis carinii in a patient with adult T cell leukemia. (6/1703)

A 48-year-old woman was admitted to our hospital with high fever, chills, cough, and exertional dyspnea. On admission, the chest roentgenogram and computed tomography scan showed bilateral alveolar infiltration in the middle and lower lung fields. Microscopic examination of the bronchial lavage fluid showed flower cells typical for adult T-cell leukemia (ATL) and cysts of Pneumocystis carinii, and Legionella pneumophila serogroup 1 grew on buffered charcoal yeast extract (BCYE)-alpha agar. The patient was successfully treated with antibiotics including trimethoprim/sulfamethoxazole, erythromycin, and sparfloxacin. Remission of ATL was achieved after three courses of antileukemic chemotherapy. Mixed infection of opportunistic pathogens should be considered in patients with ATL.  (+info)

A resuscitated case from asphyxia by large bronchial cast. (7/1703)

A 62-year-old woman with bronchiectasis suffered from asphyxia due to a large bronchial cast that obstructed the bronchial tree. Immediate bronchoscopic suction of a bronchial cast of 17 cm in length through the intubated tube relieved the patients without any complications. Large bronchial casts appear to be rare in this century but it should be considered in patients with acute exacerbation of excessive sputa not only in patients with asthma or allergy but also in patients with respiratory tract infection.  (+info)

Clinical studies of styrene workers: initial findings. (8/1703)

Styrene monomer is a high volume chemical used chiefly in production of polystyrene. A clinical survey of 493 production workers was undertaken at the oldest and largest monomer production, polymerization, and extrusion facility in the U.S. Relative exposure durations and levels were obtained from occupational histories. Significant differences between the high and low exposure groups were found with regard to history of acute prenarcotic symptoms, acute lower respiratory symptoms, prevalence of FEV 1/FV less than 75 per cent, and elevated GCTP. Other liver function tests, chest x-ray, FVC less than 80 per cent, and hematological parameters showed no distinct pattern. A concomitant mortality study has been mounted and is in progress.  (+info)

Results A total of 62 foreign bodies were detected in 39 patients, of whom 19 were investigated with LODOX and 20 with conventional digital chest radiography. Thirty-three foreign bodies were located in the two upper abdominal quadrants, 21 in the lower quadrants-which are not visible on conventional digital chest radiography-seven in the oesophagus and one in the bronchial system. The sensitivity and specificity of digital chest radiography were 44.4% and 94.1%, respectively, and for the LODOX Statscan 90% and 100%, respectively. The calculated mean radiation dose for LODOX investigations was 184 μS, compared with 524 μS for digital chest radiography.. ...

Conventional chest radiography is a relatively low-cost, widely available modality performed with low radiation dose and remains mainstay of daily practice of chest radiology. However, the low sensitivity for small pulmonary nodule limits its application in detection of early lung cancer [3, 4]. With advances in digital chest radiography, development of new techniques including algorithms typically coupled with methodological innovations that use imaging physics to improve conspicuity, and image subtraction strategies has been shown to improve image quality of digital imaging systems over conventional film techniques [18, 19]. Dual-energy subtraction radiography is considered as one of emerging technologies that can distinguish bone from soft tissue by selective decomposition and visualization of bone and soft tissue images using the information about energy-dependent changes in the attenuation of different materials [20, 21]. Multiple studies have shown that dual-energy subtraction images ...

Whether the detected prospective abnormal shadow is malignant or benignant is judged, and the information on the prospective abnormal shadow is output in such a manner that whether the prospective abnormal shadow is malignant or benignant can be distinguished.
Chest Radiographs are the most commonly ordered diagnostic image in the pediatric population. These images are encountered often in both the early medical school curriculum and outside in the clinical setting. This module was generated with the goals of giving a framework for approaching pediatric chest x-rays, as well as showcasing common radiographic findings, both normal and pathologic.
According to an article in the German Medical Journal Deutsches Ärzteblatt Jg.117 Heft 14 3. April 2020 the Munich Hospital Rechts der Isar started a new and simple scheme for COVID-19 detection: Patients with a history of fever or temperature >37.3°C / 99.1°F and a lymphocyte count ,1,1 G/L get an immediate low-dose chest CT scan. This procedure is referenced to the Therapeutic and triage strategies for 2019 novel coronavirus disease in fever clinics published recently in Lancet online at https://www.thelancet.com/pdfs/journals/lanres/PIIS2213-2600(20)30114-4.pdf.. The sensitivity of laboratory PCR tests is low according to the study and laboratory results may last for up to 3 days. A chest CT scan takes a few minutes, and the result is available shortly later. Any detected viral pneumonia in a chest CT scan indicates a COVID-19 infection after exclusion of influenza or RSV. Chest CT scans shall be typically acquired in low dose technique without contrast agent with a slice thickness of ...

Errors in chest radiology are caused by improper technique, by failure to interpret results correctly, or by inadequate knowledge of the patientss clinical history on the part of the radiologist.
Most illnesses caused by pandemic influenza A (H1N1) pdm09 virus (A/H1N1) infection are acute and self-limiting among children. However, in some children, disease progression is rapid and may require hospitalization and transfer to a pediatric intensive care unit (PICU). We investigated factors associated with rapid disease progression among children admitted to hospital for A/H1N1 infection, particularly findings on initial chest radiographs. In this retrospective study, we investigated the records of children who had received a laboratory or clinical diagnosis of A/H1N1 infection and were admitted to the largest childrens hospital in Japan between May 2009 and March 2010. The medical records were reviewed for age, underlying diseases, vital signs on admission, initial chest radiographic findings, and clinical outcomes. According to chest radiographic findings, patients were classified into 4 groups, as follows: [1] normal (n = 46), [2] hilar and/or peribronchial markings alone (n = 64), [3]

Background: Certain pulmonary diseases are associated with cardiovascular disease (CVD). Whether pulmonary, mediastinal and pleural chest CT abnormalities reflecting these pulmonary diseases improve CVD risk estimation beyond what is possible with cardiovascular findings is unknown. To evaluate the incremental predictive value of pulmonary, mediastinal and pleural findings over cardiovascular imaging findings.. Methods: The cohort comprised 10 410 patients, who underwent diagnostic chest CT for non-cardiovascular indications. Using a case-cohort approach, CT scans from the cases and from a ≈10% random sample of the baseline cohort (n=1366) were visually graded for cardiovascular, pulmonary, mediastinal and pleural findings (Figure ). Using Cox proportional hazards analysis, two models were pre-specified: Model 1 comprising the cardiovascular imaging findings; Model 2 comprised the cardiovascular plus pulmonary, mediastinal and pleural imaging findings. We evaluated the incremental value of ...

Lung cancer CT screening is one of the most accurate diagnostic tools for finding lung cancer at an early stage, when it is most treatable. CT scans of the lung are able to detect small abnormalities in the lungs that could be the beginning stages of lung cancer. These indicators are often not visible on a routine chest X-ray. Since a CT lung screening offers the best opportunity for successful treatment of lung cancer before symptoms are noticed, more physicians are opting for lung cancer screening based on risk factors (like smoking and family history), rather than symptoms. ...

The I-CNN and D-CNN models were trained on 1000 chest X-ray images, both positive and negative, for tuberculosis. Feature extraction was conducted using VGG19, InceptionV3, ResNet50, DenseNet121, and InceptionResNetV2. Age, weight, height, and gender were recorded as demographic variables. The area under the receiver operating characteristic (ROC) curve (AUC) was ...
Tree-in-bud appearance represents dilated and fluid-filled (i.e. pus, mucus, or inflammatory exudate) centrilobular bronchioles. Abnormal tree-in-bud bronchioles can be distinguished from normal centrilobular bronchioles by their more irregular appearance, lack of tapering or knobby/bulbous appearance at the tip of their branches. The tree-in-bud distribution is often patch throughout the lung. ...
USG can detect as little as-3-5 milliliters of fluid in the pleural cavity. It is usually echo-free and changes its shape with respiration. Transudates are usually sonolucent; exudates may contain floating echoes, fibrin strands, septations, s/o inflammatory, or neoplastic etiology. ...
2 years of age were obese, comparatively less than in pediatric patients from the national US cohort (30%). Lymphopenia was common and noted in approximately half of our children (mostly among those older than 4 years of age) compared to other reports (20). None of them had clinical myositis (21). No child had invasive bacterial co-infection, but 2/3rd of cases received systemic antibiotics. Although bacteriology cultures were less revealing, focal radiograph findings in our study and 2 recent reports on H1N1 illness demonstrating frequent concurrent bacterial infections in 29-43% of subjects underscore the importance of early recognition and treatment of bacterial infection on admission in SOIV illness (22). Abnormal chest radiographs were least common among youngest patients, while ½ of children , 5 years had abnormal chest x-rays, consolidation being the most common pattern as in adults. All children received Oseltamivir on day of admission and 9 pediatric patients received steroid therapy. ...

Methods Thirty-four patients with a diagnosis of CTD were included. Each patient underwent clinical examination, pulmonary function test (PFT), chest HRCT, and lung US by an experienced radiologist or rheumatologist. A second rheumatologist carried out US examinations to assess interobserver agreement. In each patient, US B-line lung assessment including 50 intercostal spaces (IS) was performed. For the anterior and lateral chest, the IS were the second to the fifth along the parasternal, mid-clavicular, anterior axillary, and medial axillary lines (the left fifth IS of the anterior and lateral chest was not performed because of the presence of the heart, which limits lung visualization). For the posterior chest, the IS assessed were the seventh to the eighth along the posterior-axillary and subscapular lines. The second to eighth IS were assessed in the paravertebral line. In each IS, the number of US B-lines under the transducer was recorded, summed, and graded according to the following ...

Tissue infiltration by neoplastic cells is rare and can involve various organs and tissues, from the bone marrow (described later) to the liver, spleen, lymph nodes, and possibly the lungs, gastrointestinal tract, kidneys, skin, eyes, and central nervous system. Pulmonary involvement in the form of masses, nodules, diffuse infiltrate, or pleural effusions is relatively rare, since the overall incidence of pulmonary and pleural findings reported for WM is only 3 5%.78-80 Cough is the most common presenting symptom, followed by dyspnea and chest pain. Chest radiographic findings include parenchymal infiltrates, confluent masses, and effusions. Malabsorption, diarrhea, bleeding, or obstruction may indicate involvement of the gastrointestinal tract at the level of the stomach, duodenum, or small intestine.81-84 In contrast to multiple myeloma, infiltration of the kidney interstitium with lymphoplasmacytoid cell has been reported in WM,85 while renal or perirenal masses are not uncommon.86 The skin ...
PET/CT played a significant role in this case in confirming a primary malignant tumor within the lung as well as providing accurate initial staging leading to prompt initiation of radiation therapy and chemotherapy. FDG-PET/CT provided a rapid way to detect extra-thoracic metastatic disease that was not evident on the initial chest CT. One known limitation of FDG-PET/CT is that it is not as sensitive as MRI for detection of brain metastases.. The value of PET/CT for staging of non-small-cell lung cancer (NSCLC) has been recognized for some time (Lardinois, D., et al)1. A recent article by Aukema et al2 focuses upon the increasing value of PET/CT for diagnosis of NSCLC as well. The authors describe the use of PET/CT in a fast track outpatient setting used to differentiate pulmonary pathology in patients referred with pulmonary symptoms and/or abnormal chest X-ray. PET/CT demonstrated a high sensitivity (97%) for diagnosing malignancy, includ-ing primary lung cancer, in patients referred to this ...

An essential part of diagnosing heart disease in cats and dogs is a comprehensive physical examination. Physical examination of the animal suspected of heart disease was covered in the previous lecture, and this lecture will focus on the use of diagnostic tests in assessment of the cardiac patient in general practice.. Thoracic Radiographs. Thoracic radiographs are essential for any patient with clinical signs of tachypnoea or dypsnoea that are potentially referable to pulmonary pathology. Radiographs should be performed cautiously in any patient with respiratory distress, minimizing additional stress and preferably while supplementing with oxygen.. In the dog with congestive heart failure, mild pulmonary oedema is characterized by perihilar alveolar infiltrates. With more significant oedema, infiltrates are evident in the caudodorsal fields, occasionally with greater involvement of the right caudal lobe. In the cat, there is no alveolar pattern specific for cardiogenic oedema, and regional or ...

There is no comparative study with long-term follow-up between posterior-only and combined posterior-anterior approaches in treating lumbar spinal tuberculosis (LSTB) and lumbosacral spinal tuberculosis (LSSTB). This retrospective study aimed to compare and evaluate the long-term outcomes of these two surgical approaches in LSTB and LSSTB. Thirty patients with LSTB and 12 patients with LSSTB underwent posterior-only approach (group A); 26 patients with LSTB and 14 patients with LSSTB were managed with combined posterior-anterior approaches (group B). Analysis and comparison in clinical and radiographic outcomes between the two groups were performed. The intra-operative bleeding amount, surgery time, and hospitalization days in group A were less than that in group B (P | 0.05). These patients were followed for a minimum of 7 years. All patients achieved completely healing within 2-year follow-up. Bony fusion was obtained in all patients. The visual analog scale, Japanese Orthopedic Association score,

Little is currently known regarding sputum smear reversion (acid-fast smear becomes positive again after negative conversion) during anti-tuberculous treatment. This study aimed to evaluate its occurrence in patients with pulmonary tuberculosis (TB) and identify factors predicting results of mycobacterial culture for smear-reversion of sputum samples. The retrospective review was performed in a tertiary referral center and a local teaching hospital in Taiwan. From 2000 to 2007, patients with smear-positive culture-confirmed pulmonary TB experiencing smear reversion after 14 days of anti-tuberculous treatment were identified. The 739 patients with smear-positive pulmonary TB had 74 (10%) episodes of sputum smear reversion that grew Mycobacterium tuberculosis in 22 (30%) (Mtb group). The remaining 52 episodes of culture-negative sputum samples were classified as the non-Mtb group. The anti-tuberculous regimen was modified after confirming smear reversion in 15 (20%). Fourteen episodes in the Mtb group and
The presence and burden of coronary artery calcium (CAC) is a strong predictor of cardiovascular events. In an effort to gain insight into the utility of CAC for coronary artery disease (CAD) screening in cancer patients with heart disease, we sought to determine the presence and burden of CAC detected on routine chest CT in patients referred to a cardio-oncology clinic, comparing them to a conventional cardiology clinic with the general population as controls. Patients from the cardio-oncology clinic, general cardiology clinic, and the general clinic population at Rush University Medical Center who had a chest CT as part of their previous treatment were identified. Each CT scan was evaluated for presence, extent, and severity of CAC by 3 independent readers. In multivariate analysis, when compared with cardio-oncology clinic, CAC was more prevalent in the CT scans of cardiology patients (p = 0.04), but not the general clinic population (p = 0.5); CAC extent (p = 0.05) and severity (p = 0.05) was

If possible, it is important to determine the extent of cancer before treatment in order to select the best treatment option. Of particular concern is the presence of cancer in lymph nodes, spread of cancer to distant sites or local extension of cancer into surrounding structures, which might make attempts to remove all cancer with surgical resection impossible. Unfortunately, in many cases the true extent of spread of cancer can only be determined by surgical resection. Frequently, more advanced cancer is found at surgery than was detected by clinical tests.. Routine Staging: All patients with esophageal cancer undergo a routine chest x-ray examination and a barium swallow under fluoroscopy (direct x-ray examination of the esophagus) as part of initial staging evaluation. All patients have computerized tomography (CT) scans of the chest, upper abdomen and possibly the neck. Unfortunately, there can be considerable error in CT scanning in detecting the extent of local spread of esophageal ...

The CT (Computed Tomography) scan or the CAT (Computer-Aided Tomography) scan is a diagnostic procedure that takes a detailed cross-sectional x-ray picture of a slice of the body.. To get a CT scan, the patient lies very still on a table, which is slowly moved horizontally while the x-ray machine rotates around the patient and takes pictures from many angles. A computer then combines the pictures into a very detailed cross-sectional image. The length of the procedure depends on the areas to be x-rayed. For the chest area, the procedure takes about 20 seconds.. CT scans can show the shape, size and the exact location of organs and tissues in any slice of the body more clearly than other diagnostic tools. This technique can help find enlarged lymph nodes, which might contain cancer that has spread from the lung. CT scans are more sensitive than routine chest x-rays in finding early lung cancers. CT scans are also used in detecting masses in the liver, adrenal glands, brain and other internal ...

The aim of this study was to evaluate the diagnostic accuracy of CAD4TB as a screening tool, implemented in the private sector in Karachi, Pakistan. This study analyzed retrospective data from CAD4TB and Xpert MTB/RIF testing carried out at two private TB treatment and diagnostic centers in Karachi. Sensitivity, specificity, potential Xperts saved, were computed and the receiver operator characteristic curves were constructed for four different models of CAD4TB. A total of 6,845 individuals with presumptive TB were enrolled in the study, 15.2% of which had MTB + ve result on Xpert. A high sensitivity (range 65.8-97.3%) and NPV (range 93.1-98.4%) were recorded for CAD4TB. The Area under the ROC curve (AUC) for CAD4TB was 0.79. CAD4TB with patient demographics (age and gender) gave an AUC of 0.83. CAD4TB offered high ...

In the suspected or confirmed COVID-19 patients chest imaging played a significant role by helping in early diagnosis and the treatment planning. Most of the COVID-19 patients showed typical findings of pneumonia on Chest X-ray.. Though CT scan of the chest is more reliable for COVID-19 diagnosis but it is not a readily available resource. Even when it is available it is not as feasible as an x-ray for patients and it requires detailed training for quick diagnosis. On the other hand chest x-ray is an easier way to immediately diagnose COVID-19 when suspected and should be promoted as a tool.. Chest x-ray has a reasonably good sensitivity and can be used as an empirical method in the emergency setting, reducing risk of ICU admission.. The findings seen most frequently are the airspace opacity described as consolidation or ground-glass opacity present bilaterally on the lower lobe mainly. COVID 19 is spreading globally very rapidly and massively. The whole medical fraternity is under pressure to ...
Because of their high zinc content modern U.S. pennies that become lodged in the esophagus may react with stomach acid thereby damaging the esophageal mucosa. Management of esophageal pennies may therefore differ from that of other esophageal coins making differentiation of pennies from other coins important. We reviewed the records of 111 children who underwent endoscopic esophageal coin removal over a 19-year period to determine the ability of history and size of esophageal coin images on posterior-anterior and lateral chest radiographs alone and in combination to differentiate esophageal pennies from other esophageal coins ...
Chest X-ray is abnormal in the majority of patients with pulmonary hypertension (PH); however, there is no correlation between the severity of PH and the findings on chest X-ray. Findings of PH on chest X-ray include pulmonary artery dilatation and right sided enlargement of the heart. Chest X-ray allows the exclusion of left heart disease and lung disease that can lead to group 2 and group 3 PH, respectively. ...
Tuberculosis is an infectious disease and becomes a major threat all over the world but still diagnosis of tuberculosis is a challenging task. In literature, chest radiographs are considered as most commonly used medical images in under developed countries for the diagnosis of TB. Different methods have been proposed but they are not helpful for radiologists due to cost and accuracy issues. Our paper presents a methodology in which different combinations of features are extracted based on intensities, shape and texture of chest radiograph and given to classifier for the detection of TB. The performance of our methodology is evaluated using publically available standard dataset Montgomery Country (MC) which contains 138 CXRs among which 80 CXRs are normal and 58 CXRs are abnormal including effusion and miliary patterns etc. The accuracy of 81.16% was achieved and the results show that proposed method have outperformed existing state of the art methods on MC dataset ...
Pneumonia is either the first or second most common ventilator-associated event (VAE) seen in the pediatric intensive care unit. The reported incidence varies widely among studies (from 0.3 to 45.1 per 1,000 ventilator days). The lack of a consistent, gold-standard definition for what had been traditionally referred to as ventilator-associated pneumonia (VAP) plays a large part in this variance.. The U.S. Centers for Disease Control and Prevention (CDC) defines VAP as a positive bacterial culture from a tracheal aspirate (more than 104 colony-forming units [cfu] from a sample obtained via bronchoalveolar lavage) and/or purulent secretions (more than 25 neutrophils and fewer than 10 epithelial cells per low-power field) in a patient who requires mechanical ventilation and has acutely worsening oxygenation. However, other investigators have defined VAP by the presence of pathogenic bacteria in tracheal aspirate in conjunction with new chest radiographic findings and fever or leukocytosis. Studies ...

To detect vascular changes which affect pulmonary arteries and veins differently, both compartments need to be identified. We present a novel, fully automatic method that separates arteries and veins in thoracic computed tomography images, by combining local as well as global properties of pulmonary vessels. We split the problem into two parts: the extraction of multiple distinct vessel subtrees, and their subsequent labeling into arteries and veins. Subtree ...
Survey and monitoring of usage of chest radiography and chest ultrasonography in the cardiothoracic perioperative setting. Zlatka Belamarić, Aatif Husain, Giampaolo Martinelli, Gerry Van Rensburg, Greta Giuliano, Suresh Sanapala. St Bartholomews Hospital, Barts NHS Trust, London, United Kingdom. Introduction. Respiratory complications remain a leading cause of post cardiac surgical morbidity and can prolong hospital stay and increase costs. Conventional lung imaging in critically ill patients are bedside CXR and lung CT. Lung US is also a tool for assessing lung status in critically ill patients and can be easily used and repeated at the bedside, allowing the effects of therapy to be monitored, as highlighted in the International evidence-based recommendations for point-of-care lung ultrasound published in 2012.. Objectives. 1) To survey if the LUS is utilised in the contexts where it is supported by the literature to be superior and more effective than CXR. 2) To compare if the different ...
In addition to the Transfer policy published in the CCC and TI Catalog, students applying for transfer into the radiography program shall meet the general admission, progression/dismissal, and graduation requirements according to radiography specific policies. Due to a standardized radiography curriculum in the North Carolina Community College System (NCCCS), a lateral transfer from a hospital or university based, private or out-of-state radiography program cannot be guaranteed. Neither can a lateral transfer from an NCCCS radiography program be automatically assumed. Therefore, serious students need to be willing to spend two more years @ CCCTI in pursuit of their dream.. The radiography director evaluates the students radiography transcript to determine the total number of possible radiography courses or credits allowed for transfer credit. Transfer students must meet the 2.5 GPA academic requirement in all RAD and related courses in the radiography curriculum. In the best interest of the ...

There are dark shadows on the earth, but its lights are stronger in the contrast. - Charles Dickens quotes from BrainyQuote.com
Some years ago, when I was an SHO, I questioned a consultant about the reasons for requesting a routine chest x ray on a patient who was clinically well. I was told that it was important to keep one step ahead of the patient. That response satisfied me at the time, and I have used the quote from time to time when explaining to parents the reasons for undertaking investigations in children who have no overt clinical problems. Nowadays, clinicians and families are likely to require more tangible evidence of benefit before agreeing to children undergoing detailed investigations, particularly if these may be uncomfortable or distressing. Jaffe et als retrospective review is therefore a welcome attempt to address this issue with respect to routine annual blood tests in young children with cystic fibrosis (CF).. Annual review of patients with CF has been practised for some time in most CF centres in the UK and is now recommended by national guidelines.1 The aims of annual review are numerous, but ...
Pneumonia remains a common source of morbidity and mortality in children. A key question in the diagnostic evaluation of children with acute respiratory illness is whether chest radiography should be performed to rule in or rule out the diagnosis of pneumonia. Radiologically, pneumonia is defined as an infiltrate seen on chest radiography in a child with symptoms of an acute respiratory illness.

For validation, we first use synthetically generated airways and vessels produced by the proposed generative model to compute the relative error and directly evaluate the accuracy of CNR in comparison with traditional methods. Then, in-vivo validation is performed by analyzing the association between the percentage of the predicted forced expiratory volume in one second (FEV1\%) and the value of the Pi10 parameter, two well-known measures of lung function and airway disease, for airways. For vessels, we assess the correlation between our estimate of the small-vessel blood volume and the lungs diffusing capacity for carbon monoxide (DLCO ...
EDITORIAL Genes in their environment: how can we read the riddles? Andrew Bush. MB BS (Hons) MA MD FRCP FRCPCH. Professor of Paediatric Respirology, Imperial School of Medicine, National Heart and Lung Institute, London, UK. Honorary Consultant Paediatric Chest Physician, Royal Brompton Hospital, London, UK Once upon a time, as all the best childrens stories begin, a lot of clever geneticists began a huge hunt for the asthma gene. At first they thought they had found it, but then more and more of the hunters found different asthma genes, and sometimes some gene hunters could not find the gene that previous hunters thought was the key one. Life became more and more confusing, and the root causes, which should have been thought of right from the start, have only recently begun to be identified. These include that there are many types of asthma, not likely all to have the same background, and thus careful clinical phenotyping is essential; that genes do not operate in isolation, but in their ...
This study proposes a novel automated method for cardiomegaly detection in chest X-rays (CXRs). The algorithm has two main stages: i) heart and lung region localization on CXRs, and ii) radiographic index extraction from the heart and lung boundaries. We employed a lung detection algorithm and extended it to automatically compute the heart boundaries. The typical models of heart and lung regions are learned using a public CXR dataset with boundary markings. The method estimates the location of these regions in candidate (patient) CXR images by registering models to the patient CXR.
We scurried back to the clinic to meet with Dr. Pulmonary Oncologist. This ended up being every minute worth the drive and the wait! He pulled up images of my chest CT from last February and from the recent scan. The chest CT is always taken at the same time as the PET scan. The difference between the two types of images is that the PET is colored based on the radioactivity that my cells take up, but the chest CT is more like a standard x-ray. So although the PET scan showed completely normal cellular activity, Dr. Pulmonary Oncologist scrutinized the CT images for abnormalities, which he found and showed to me. He put my pre-chemo chest CT on the left, then my January 2015 chest CT on the right. He had used the glowing data from the PET scan to find the suspected cancer nodules on the old chest CT. Then he found the matching image on the recent chest CT. What he pointed out to me is that when you look at the two CTs side by side, you can still see a trace of each nodule. He said that they are ...
Thus initial antimicrobial therapy is often empirical and is based on the setting in which the infection was acquired, the clinical presentation, patterns of abnormality on chest radiography, results of staining of sputum or other infected body fluids, and current patterns of susceptibility of the suspected pathogens to antimicrobial agents. After the etiologic agent is identified, specific antimicrobial therapy can be chosen.. Defense Mechanisms. The lung is a complex structure composed of aggregates of units that are formed by the progressive branching of the airways. Approximately 80% of the cells lining the central airways are ciliated, pseudostratified, columnar epithelial cells; the percentage decreases in the peripheral airways. Each ciliated cell contains about 200 cilia that beat in coordinated waves ~1000 times per minute, with a fast forward stroke and a slower backward recovery. Ciliary motion is also coordinated between adjacent cells so that each wave is propagated toward the ...
Why Low Dose CT Vs. Standard CT or a Chest X-ray?. Standard CT scans of the chest provide more detailed pictures than chest x-rays and are better at finding small abnormalities in the lungs. Low-dose CT of the chest uses lower amounts of radiation than a standard chest CT but it is more than the dose from a chest x-ray. So LDCT is a balance, offering the detail closer to standard CT with the radiation dose closer to a chest x-ray.. Do all imaging centers provide Low Dose CT Lung Cancer Screening?. No. Not all imaging centers have Low Dose CT scanners. Screening should only be done at facilities that have the right type of CT scanner and have developed a proper Low Dose CT imaging protocol specific for Lung Cancer Screening. University Medical Imaging was the first to provide Low Dose CT to the Rochester Community in 2006 and is the community leader in reduced dose CT.. Is this test right for me?. Low Dose CT Lung Cancer Screening is not recommended for everyone. Individuals interested in ...
