DSCT is showing that it can often do a better job in differentially diagnosing hepatocellular carcinoma (HCC), liver metastases, and cavernous hemangioma in the clinical setting.April 28, 2010CTCT calcium scores boost value of cardiac risk factorsA new analysis of a major cardiac risk study published today in the Journal of the American Medical Association found that CT coronary artery calcium scoring significantly boosts the power of traditional risk factors for predicting adverse cardiac events over the long term.April 27, 2010Digital X-RayCoronary CTA best next test for positive stress patientsAsymptomatic individuals with positive cardiac stress results should proceed to coronary CT angiography (CTA) rather than an invasive cardiac catheterization, according to a new report in the May American Journal of Roentgenology. The study found that low-risk patients received more cost-effective care by using coronary CTA as a gatekeeper test.April 22, 2010CTCT attenuation improves sensitivity for bowel wall obstructionA technique that analyzes the attenuation of small regions of interest in the bowel wall at CT can improve the diagnosis of suspected bowel wall ischemia, a condition associated with substantial morbidity and mortality, according to a study in the April American Journal of Roentgenology.April 18, 2010CTSmall colon polyps on VC suggest presence of larger lesionsIndividuals with several diminutive colon polyps on virtual colonoscopy studies are far more likely than other screening subjects to also have a larger colorectal lesion, say researchers from the University of Munich in Germany.April 15, 2010CTAutomated exposure control delivers uneven CT dose reductionReducing tube current may be a popular way to lower CT radiation dose, but it's not necessarily an effective one. In a new study, medical physicists from Greece found that organ dose reductions resulting from tube current modulation with automated exposure control can vary -- especially in children.April 14, 2010CTCT shows abdominal fat is unreliable Crohn's treatment targetA few reports have associated abdominal visceral fat with more aggressive forms of Crohn's disease, but the strength of the association -- and the implications for treatment -- remain unclear. Researchers from Ireland decided to try CT to resolve the issue.April 13, 2010CTLess DNA damage seen after high-pitch coronary CTAHigh-pitch dual-source CT angiography (CTA) scans produce significantly less radiation-related DNA damage than comparable low-pitch dual-source CTA scans -- and, importantly, the DNA results correspond to both measured and derived biological radiation doses, say researchers from Erlangen, Germany.April 8, 2010UltrasoundCarotid ultrasound may help predict cardiac eventsPerforming ultrasound studies of carotid intima-media thickness provides long-term prognostic value for adverse cardiac events, giving doctors important clues about who is at risk for a heart attack, according to a study published April 6 in the Journal of the American College of Cardiology.April 7, 2010Previous PagePage 127 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
