Eric Barnes[email protected]CTEnhanced reference standard boosts CTA accuracyBorrowing a technique from the virtual colonoscopy playbook, researchers from South Carolina and Germany found that coronary CT angiography (CTA) is better than previously thought compared to catheter-based coronary angiography -- in fact the two tests are essentially equivalent, they said.August 3, 2010CTWorkshop yields big drop in scan radiation doseScan data from 10 radiology practices in Australia showed that attendance at a radiation dose-optimization workshop nearly halved the doses subsequently given to patients, according to a study published online in the Journal of the American College of Radiology.August 1, 2010Image ProcessingContrast US processing tool shows malignant liver lesionsSwiss researchers have developed a real-time parametric imaging technique for distinguishing benign from malignant liver lesions easily and noninvasively using contrast-enhanced ultrasound. In its first clinical run, the method delivered high sensitivity and specificity in a patient cohort.July 29, 2010CTSupersized CONFIRM trial tackles coronary CTA and mortalityIn a study that probes what may be the largest database of detailed coronary CT angiography (CTA) results assembled to date, New York City researchers found an integral association between coronary artery disease and mortality at coronary CTA in patients without known heart disease.July 29, 2010CTVC not cost-effective -- unless screening rates riseIn a new model analysis published Tuesday in the Journal of the National Cancer Institute, virtual colonoscopy was generally less cost-effective than several other colon cancer screening tests, including conventional colonoscopy. However, VC would become the most cost-effective test if it were to increase colon cancer screening rates.July 26, 2010CTNewer dosimeters find big errors in head CT perfusion dosesTraditional radiation dose measurements are grossly inaccurate for perfusion CT head scans, which are being performed with increasing frequency for patients with suspected stroke, according to a study presented on July 22 at the American Association of Physicists in Medicine meeting in Philadelphia.July 26, 2010Cardiac ImagingAuntMinnie.com Cardiac Imaging InsiderJuly 25, 2010CTAuntMinnie.com CT InsiderJuly 21, 2010CTPancreatic CT pitfalls can be avoidedEvaluating pancreatic CT images to determine resectability is one of the more difficult jobs in radiology, perhaps more so because the stakes are so high. But a lot of mistakes can be avoided with 3D imaging and careful attention to a few details.July 21, 2010CTConebeam reconstruction method speeds processing, cuts doseA new processing method for conebeam CT images promises to dramatically lower radiation exposure for patients undergoing perfusion CT prior to image-guided radiation therapy, according to a study presented at the American Association of Physicists in Medicine meeting in Philadelphia.July 20, 2010Previous PagePage 121 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
