Eric Barnes[email protected]CTDose experts look at radiation risk, error, and uncertaintyWhat's the latest on risk from medical radiation? It all depends on the exam and the patient, of course, but knowledge is evolving, and some newer evidence suggests higher risks from smaller doses, according to speakers presenting last Friday at a Washington, DC, symposium.December 11, 2011CTRadiation symposium: Dose tracking calls for collaboration, technologyExperts from around the world convened in Washington, DC, today for a two-day symposium on finding better ways to track and utilize medical radiation dose. Collaboration is key, speakers said, because the problem of tracking radiation dose is so big that no single country or governmental agency can solve it alone.December 7, 2011CTSame CCTA results mean different risks in men and womenCHICAGO - Researchers have long known of differences between men and women in the rate of cardiac disease and resulting morbidity, but a new study presented at RSNA 2011 suggests that the same coronary CTA (CCTA) results require different interpretation and risk assessments depending on the patient's gender.December 4, 2011CTEasy 1-day VC prep delivers high sensitivityCHICAGO - Virtual colonoscopy using a same-day bowel preparation showed high diagnostic accuracy and equally high patient satisfaction in a study from Italy presented on Wednesday at the RSNA 2011 meeting.November 29, 2011ISACR's CT dose registry goes for quality, quantityCHICAGO - The American College of Radiology's (ACR) Dose Index Registry pilot project has already amassed a critical number of studies, while developing ways to keep the data accurate despite wide variations in practice patterns and study nomenclature, according to a Wednesday presentation at RSNA 2011.November 29, 2011Nuclear MedicineImaging evolves to lead atherosclerosis careCHICAGO - The management of atherosclerosis, the No. 1 cause of death in the U.S., has been reinvented by advances in imaging technology, according to a panel presentation on Sunday at the RSNA 2011 meeting.November 27, 2011CTHigh-pitch coronary CTA limited to slower heart ratesContrary to some previous studies, high-pitch, dual-source coronary CT angiography (CCTA) scans should be reserved for patients with the slowest heart rates, according to a new study published in the December issue of Radiology.November 24, 2011CTVC lures more screening participants than colonoscopyWhen offered virtual colonoscopy for colorectal cancer screening, substantially more individuals accepted the invitation compared with those who were offered conventional colonoscopy, Dutch researchers reported online November 15 in Lancet Oncology.November 20, 2011CTAHA: CT calcium scoring broadens heart attack risk predictionCT-based calcium scoring is a strong predictor of heart attacks in the young and old, not just the typical middle-aged individual at intermediate risk, according to a study presented on Wednesday at the 2011 American Heart Association (AHA) meeting in Orlando, FL.November 16, 2011CTAHA: CCTA demonstrates low rate of downstream proceduresFor as long as 2.5 years after undergoing coronary CT angiography (CCTA), invasive angiography and revascularization are uncommon, even in patients with significant coronary artery disease at CT, according to a report presented on Tuesday at the American Heart Association (AHA) meeting.November 15, 2011Previous PagePage 93 of 258Next PageTop StoriesMRIMRI may help guide brachial plexus surgeryMRI-based volumetric analysis of paraspinal muscles can distinguish the severity of traumatic brachial plexus injury.AIShould hospitals pursue local domain LLM adaptation for radiology reports?Womens ImagingMRI model predicts breast tumor shrinkage patternsMRICheck for middle neck involvement for nasopharyngeal cancer prognosisMolecular ImagingPET links brain receptor to emotional numbing in PTSD
