Eric Barnes[email protected]CTVirtual colonoscopy use rises in U.S. hospitalsMedicare doesn't cover most virtual colonoscopy exams, but the lack of reimbursement hasn't stopped more and more hospitals from offering the service, concludes a new study in the March Journal of the American College of Radiology.March 1, 2011CTDynamic cardiac CT stress perfusion equivalent to MRICardiac MRI may be the gold standard for evaluating myocardial perfusion, but there's no reason CT can't eventually take over much of MRI's workload in patients suspected of coronary artery disease, say researchers from the Medical University of South Carolina and two other centers.February 28, 2011CTNIH summit mulls methods to lower CT doseIn the quest for the sub-mSv CT exam, a number of methods can be called upon to reduce CT dose, presenters said in a summit sponsored by the U.S. National Institutes of Health (NIH), the American College of Radiology, and the Coalition for Imaging and Bioengineering Research.February 24, 2011Cardiac ImagingAuntMinnie.com Cardiac Imaging InsiderFebruary 24, 2011CTDialysis patients at higher risk from multiple CT scansDialysis patients receive more frequent medical imaging exams, particularly CT, and hence more radiation exposure than the population as a whole, putting them at increased risk of developing cancer, according to a new study in the Journal of the American Society of Nephrology.February 24, 2011CTBismuth thyroid shielding cuts CT dose without excessive noiseIn a new study that tested phantoms as well as patients, a commercially available bismuth shield for the thyroid gland substantially reduced CT radiation dose without a corresponding increase in image noise, according to results published in the March American Journal of Roentgenology.February 22, 2011CT4D CT evaluates dynamic wrist instabilitiesIt's not up for an Academy Award, but a new action movie starring a painful wrist could help doctors detect subtle dynamic joint instabilities that can be seen only in motion. Researchers showed how nongated 4D CT scans offer a way to diagnose these instabilities at an early stage, allowing early intervention.February 21, 2011CTHigh-pitch DSCT cuts pulmonary embolism scan doseUsing high-pitch dual-source CT (DSCT) to rule out pulmonary embolism delivers the same image quality as both conventional MDCT and standard-pitch dual-energy CT -- but at a significantly lower radiation dose, according to a new study from Austria.February 17, 2011CTAuntMinnie.com CT InsiderFebruary 16, 2011CT320-row perfusion CT finds malignant lung nodulesOwing to its high resolution and wide anatomic coverage, dynamic first-pass perfusion 320-detector-row CT outperforms PET/CT for distinguishing benign from malignant lung nodules, researchers from Japan report in Radiology.February 15, 2011Previous PagePage 107 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?
