The results suggest that polyps of the same size detected at virtual colonoscopy could be classified and managed differently based on their morphology.December 21, 2009CTLawsuit hits GE in Alabama CT overdose caseAttorneys in Huntsville, AL, have filed suit in federal court against GE Healthcare of Chalfont St. Giles, U.K., on behalf of a patient who allegedly received excessive radiation during a CT perfusion head scan for suspected stroke.December 17, 2009MRIMRI shows age- and gender-based differences in myocardial motionPeople who suspect that men's and women's hearts march to different drummers now have proof from cardiac MRI. Myocardial motion is strongly influenced by gender as well as age, according to researchers from Freiburg, Germany.December 17, 2009CTCT treads MRI turf by diagnosing myocardial edemaThe visualization of pericardial fluid associated with myocardial infarction, long the exclusive province of cardiac MRI, can be performed using CT, say researchers from the University of Aachen in Germany.December 16, 2009CTCAD catches most flat polyps on virtual colonoscopyComputer-aided detection (CAD) is sensitive for all but the flattest of flat colorectal lesions, even in minimally prepped patients, according to a new study from Italy. Using CAD, radiologists significantly improved their ability to detect the elusive polyps, which can harbor precancerous lesions.December 15, 2009CTStudies spotlight high CT radiation dose, increased cancer riskTwo studies appearing in this week's Archives of Internal Medicine reveal higher-than-expected radiation dose in clinical CT studies and increased lifetime potential cancer risks as a result. At a minimum, the U.S.-funded studies suggest that dose-reduction efforts have not spread widely enough across the U.S.December 13, 2009CTASIR cuts dose in Crohn's disease patientsCHICAGO - Low-dose abdominal CT images reconstructed with an adaptive statistical iterative reconstruction (ASIR) technique are equivalent -- and, in fact, slightly better in quality -- than standard-dose images reconstructed with filtered back projection.December 3, 2009CTLiver metastases more conspicuous at low-energy DSCTCHICAGO - Hypovascular liver lesions are better visualized at lower photon energies in dual-source CT (DSCT), say researchers from New York City.December 2, 2009CTContrast dose halved in coronary CTACHICAGO - Contrast doses for CT angiography (CTA) are too high, but they can be lowered substantially with the right equipment and careful attention to technique, according to researchers from Charité University Medical School in Berlin.December 1, 2009Previous PagePage 134 of 258Next PageTop StoriesDigital X-RayChest x-rays reveal atherosclerosis in patients undergoing amputationsLower limb amputation is an increasingly common major complication of advanced peripheral arterial disease and diabetes mellitus.MRI3D MRI technique helps plan treatment for pediatric heart conditionsWomens ImagingCould AI scoring help with managing DCIS?CTClinicians, beware: CT diagnostic accuracy varies by adnexal lesion typePractice ManagementRadiology coding update for 2026
