Eric Barnes[email protected]CTCT alters management, cuts hospital admissions in the EDCT not only improves the management of abdominal pain patients in the emergency department (ED), it also reduces hospital admissions significantly while boosting diagnostic confidence, according to a new study published in the February edition of the American Journal of Roentgenology.January 23, 2011CTStudy confirms accuracy of VC for bone mineral density examsCT data from virtual colonoscopy (VC) studies are ideal for assessing bone mineral density, say researchers from the University of Wisconsin. They found that VC data from the lumbar spine showed excellent correlation with bone density's gold standard, dual-energy x-ray absorptiometry.January 19, 2011CTHigh-pitch CT cuts dose for patients with low heart ratesAustrian radiologists have found a way to cut the radiation dose of coronary CT angiography studies to as low as 1 mSv by using a high-pitch scanning protocol on a 128-slice scanner for patients with low heart rates.January 16, 2011CTDual-energy CT halves contrast dose for PE assessmentPulmonary embolism (PE) rule-outs can be done with half the normal contrast dose using dual-energy CT -- on a single-source scanner. Researchers from Canada believe their new protocol is robust enough to open up a critical diagnostic test to patients who weren't candidates for CT pulmonary angiography.January 13, 2011CTMDCT shows high accuracy for identifying bullet trajectoriesA new study in the March issue of Radiology touts CT as an efficient, effective way to analyze wounds from bullets and explosive devices. The wars in Iraq and Afghanistan mean that U.S. troops face threats from increased sniper activity and the use of improvised explosive devices, according to the study.January 10, 2011CTColon cancer incidence drops sharply after colonoscopyColonoscopy is associated with substantial reductions in colorectal cancer incidence, according to a new study. Colonoscopy reduced cancer risk by 77% overall, and in contrast to other recent studies, it protected both the left and right sides of the colon.January 9, 2011CTBig CTA trial shows coronary plaque risk in low-risk patientsPeople considered to be at low risk for coronary artery disease aren't so low-risk after all, according to early results from a large coronary CT angiography (CTA) screening study in Korea.January 6, 2011Cardiac ImagingAuntMinnie.com Cardiac Imaging InsiderJanuary 3, 2011CTLarge study shows exams using radiation are common in childrenChildren undergo many imaging procedures involving radiation, concludes a new study from the University of Michigan and other U.S. centers. The three-year study covering more than 350,000 children with health insurance showed that the subjects received, on average, three scans involving radiation over the study period.January 3, 2011CTDual-phase DECT myocardial perfusion cuts time, doseThere's no need to acquire images during both stress and rest phases in dual-energy CT (DECT) myocardial perfusion imaging, say researchers from the U.S. and Germany. A stress phase combined with a delayed-enhancement phase performs just as well while reducing radiation dose by a third.January 3, 2011Previous PagePage 109 of 258Next PageTop StoriesWomens ImagingAuditing preop MRIs is feasible under upcoming BI-RADS recommendationsGoing by the upcoming BI-RADS manual resulted in metrics that were within expected ranges based on prior data.Womens ImagingSocial adversity tied to TNBC incidence rates in Black womenPractice ManagementWhat radiology practices need to know about the federal government shutdownMolecular ImagingPET/CT shows value in patients with soft-tissue sarcomasSponsor ContentRegister Now: Breaking Barriers in Breast Imaging Webinar
