Eric Barnes[email protected]CTACRIN virtual colonoscopy training tied to performanceIn the first of several upcoming studies that will analyze the ACRIN 6664 trial data, researchers examined the role of training and testing in reader performance interpreting virtual colonoscopy studies. They found that training improved overall reader sensitivity in predictable, quantifiable ways -- and that novice readers could be trained to perform as well as more experienced colleagues.October 26, 2008CTVC finds perforations from incomplete colonoscopyNew research suggests that occult colonic perforation after incomplete optical colonoscopy may be more common than previously thought. The study, which recommends low-dose CT scanning of incomplete colonoscopy patients before VC, could have workflow and patient-safety implications in facilities that routinely perform same-day VC.October 23, 2008Digital X-RayCTA less costly than angiography for carotid artery occlusionThe results of a new cost-effectiveness analysis suggest that using CT angiography (CTA) to confirm suspected carotid occlusion is more cost-effective than catheter angiography. The study represents a rare look at the cost-effectiveness of the use of CTA for carotid disease.October 21, 2008CTNew neuroimaging potential seen in 320-row CTThe development of dynamic volume imaging with 320-detector-row CT is opening new diagnostic and therapeutic windows to the brain, according to researchers at a high-volume imaging facility in Las Vegas.October 19, 2008CTAuntMinnie.com CT InsiderOctober 14, 2008CTAutopsy study confirms low prevalence of adenomas in youthA rare autopsy study of more than 3,500 individuals found that the incidence of colorectal adenomas is low in those under 50, but rises sharply in the sixth decade of life. The study, which provides important new information about the natural history of colorectal polyps and cancer in the young, supports current guidelines recommending that screening begin at age 50.October 13, 2008Digital X-RayACRIN study: Cardiac CTA cheaper, more effective for chest pain triageA University of Pennsylvania study of acute chest pain patients found that cardiac CT angiography (CTA) was a better triage method than the traditional standard of care, according to results presented earlier this month at the American College of Radiology Imaging Network (ACRIN) fall meeting.October 13, 2008Image ProcessingFaster respiratory motion prediction aids radiotherapyRespiratory motion compensation algorithms are helping to reduce the irradiation of healthy tissues during radiotherapy by compensating for the patient's breathing during treatment. Researchers from Germany have developed new algorithms that reduce the computational burden of motion-tracking algorithms while maintaining accuracy.October 9, 2008CTDual-energy CT helps distinguish malignant lung nodulesResearchers in South Korea used a dual-energy CT (DECT) scan to perform a lung imaging task that previously required two scans, reducing the radiation dose needed for the workup. The group found that DECT enabled the detection of both contrast enhancement and lung nodule calcifications in a single scan.October 7, 2008BreastMRI beats mammo for gauging breast cancer treatment responseARLINGTON, VA - MRI is superior to mammography for evaluating response to neoadjuvant chemotherapy for breast cancer, according to early trial results from the University of California, San Francisco and nine other U.S. academic centers. The results were presented at last week's American College of Radiology Imaging Network (ACRIN) fall meeting.October 6, 2008Previous PagePage 155 of 258Next PageTop StoriesPractice ManagementMalpractice factors tied to imaging use in emergency departmentSeveral liability and damage caps are tied to less imaging being used for patients who present with a headache.Womens ImagingExperts, research highlight prevalence of remote breast imagingUltrasoundAblation procedures cure thyroid disorders in older patientsPractice ManagementNYU researcher's new book explores how imaging is 'changing our world'Sponsor ContentJoin Us!
