Eric Barnes[email protected]CTFlaxseed offers radiation protection in animal studyDietary flaxseed protects against the harmful effects of radiation, according to a new study in BMC Cancer, which found that the foodstuff when given to mice not only protected tissues before radiation exposure occurred, it reduced damage after exposure as well.August 11, 2011CTRise in CT use linked to drop in hospital admissionsCT use in emergency departments has risen sharply in the past decade, and it's not hard to find opposition to the kinds of growth numbers that some find alarming. But there has been little opposition to an ongoing drop in hospital admissions, and now a study in the Annals of Emergency Medicine has linked the two trends.August 10, 2011CTColonoscopy, virtual and real, less cost-effective than stool testsVirtual and conventional colonoscopy were both beneficial but less cost-effective for preventing colorectal cancer than stool screening plus flexible sigmoidoscopy -- though virtual colonoscopy may have benefits for screening laggards -- according to a new model analysis in Radiology.August 8, 2011CTScoring tool predicts coronary CTA success before scanResearchers have developed a tool that predicts whether coronary CT angiography (CCTA) will be successful before subjecting patients to the time, expense, and risks of scanning, according to a study published in Circulation: Cardiovascular Imaging.August 4, 2011CTCT guidance tool halves dose by skipping redundanciesCT has become increasingly popular for guiding interventional procedures such as needle placements, but these scans may be packing more dose than necessary. Researchers in China have found a way to cut the radiation dose by eliminating the need to perform multiple scans of the same area.August 3, 2011CTJACR articles address dose reductions in CTRadiation dose from CT can be reduced significantly, according to a pair of articles in the current issue of the Journal of the American College of Radiology. The articles provide tips on topics ranging from technical scanning parameters to staff training and quality control.August 2, 2011CTSmoothing algorithm primes CAD for low-dose VCBoston researchers have come up with a tool to reduce image noise in ultralow-dose virtual colonoscopy, paving the way toward computer-aided detection (CAD) that is compatible with today's ultralow-dose scanning techniques.August 1, 2011CTHigh-pitch stent assessment drives down dosePhysicians in Singapore are evaluating stent patency using extremely low radiation doses with the aid of dual-source MDCT, according to a presentation at the recent Society of Cardiovascular Computed Tomography meeting in Denver.July 31, 2011CTQuantitative CT links COPD type and severity with flare-upsCT can detect both the type and severity of chronic obstructive pulmonary disease (COPD), helping predict which patients will experience exacerbations, according to a new study published online in Radiology.July 28, 2011CTAuntMinnie.com Virtual Colonoscopy InsiderJuly 27, 2011Previous PagePage 100 of 258Next PageTop StoriesMolecular ImagingPET links brain receptor to emotional numbing in PTSDTo date, only a single study has investigated CB1R availability in humans exposed to trauma.Womens ImagingCEM, DBT show promise for preoperative breast cancer stagingMRIMRI illumines how the brain maintains 'representation' of phantom limbsDigital X-Ray3D DEXA reveals lower bone density in diabetes patientsMRIGadolinium in ... beer?
