Most lesions were resectable, but most were seen only when the images were read using wider fields-of-view (FOV).May 25, 2010CTJapanese group finds lower VC sensitivity for carpet lesionsSome lateral spreading tumors, more commonly known as carpet lesions, can be hard to spot on virtual colonoscopy, say researchers from Japan, although others say the lesions are readily visible, noting VC's known shortcomings in detecting some flat lesions.May 25, 2010CTCalif. radiation bill up for Senate discussionA bill that would require medical imaging facilities to record the radiation dose from any exam that delivers ionizing radiation is scheduled for discussion on the floor of the California Senate today.May 23, 2010CTLarge study confirms CT's accuracy for acute appendicitisSAN FRANCISCO - One of the largest CT studies to date of acute appendicitis has confirmed the modality's sky-high diagnostic accuracy. The results also showed that CT is relatively insensitive to imaging technique, though the researchers said they have come to favor the use of oral contrast.May 19, 2010CTReduced-voltage cardiac CT works fine -- if you know the rulesSAN FRANCISCO - Backed by growing clinical evidence, radiologists should step up to the plate and cut the tube voltage in their cardiovascular CT protocols. But getting the benefits without the pitfalls means paying attention to some technical considerations.May 18, 2010CTACC task force releases 2010 policy on CTA, CMRThe American College of Cardiology (ACC) Foundation Task Force on Expert Consensus Documents has published the 2010 version of its views on coronary CT angiography (CTA) and cardiac MRI (CMR), detailing the strengths and weaknesses of each technology.May 18, 2010CTMBIR aims to outshine ASIR for sharpness, CT dose reductionRecent studies indicate that CT scanning with an adaptive statistical iterative reconstruction (ASIR) algorithm offers better image quality at a lower radiation dose. But a new algorithm, called model-based iterative reconstruction (MBIR), could be even better, according to a presentation today at the International Society for Computed Tomography meeting.May 17, 2010Industry NewsLos operadores de caterización cardíaca reciben altas dosis de radiaciónEl desarrollo rápido de nuevos stents cardíacos y otros dispositivos médicos está abriendo un mundo de posibilidades para procedimientos intervencionistas en los laboratorios de caterización cardíaca, pero también está exponiendo los operadores de los equipos a dosis crecientes de radiación.May 16, 2010CTJACC special issue tackles radiation dose in cardiac imagingA series of editorials in this month's Journal of the American College of Cardiology examines radiation risk from cardiac imaging exams, and asks if the benefits of imaging have been understated in the risk-benefit equation to the detriment of patient care.May 13, 2010Previous PagePage 125 of 258Next PageTop StoriesInterventionalDoes advanced imaging in stroke patients improve outcomes?Conventional or advanced imaging selection of EVT patients did not result in significant differences in 90-day clinical outcomes.CTSafety concerns lead to suspension of CT service at Belgian hospitalCTCentrally located lung cancer may lead to poor patient outcomesCTVideo: Perry Pickhardt on CTC, the 'best kept secret in medicine'Molecular ImagingExperts issue appropriate use criteria for molecular breast imaging
