Eric Barnes[email protected]CTIterative reconstruction cuts CT dose for urinary stone diseaseIterative reconstruction allows steep CT radiation dose reductions in urolithiasis imaging without loss of image quality or diagnostic confidence, researchers from Massachusetts General Hospital have found. The results may help allay fears of potentially excessive radiation in these oft-repeated scans.August 19, 2012CTCCTA equal to cardiac cath for guiding CAD therapy choicesCoronary CT angiography (CCTA) was nearly perfectly in line with cardiac catheterization in its selection of therapies for patients with a high likelihood of coronary artery disease (CAD), according to a new study in Radiology. The results showed that CCTA can determine patient management as well as invasive angiography while sparing many patients from invasive procedures, researchers said.August 12, 2012CTAlgorithm boosts temporal resolution in CCTAToday's cardiac CT is more robust than ever, broadening the range of patients who can be imaged. One new tool improves all-important temporal resolution even in midrange scanners. The software creates a hybrid sample of image data to improve temporal resolution in cardiac CT angiography (CCTA) images of obese patients.August 9, 2012CTPhysician education busts inappropriate CCTA useA study of more than 25,000 patients in Michigan shows that inappropriate use of coronary CT angiography (CCTA) can be drastically curtailed by educating the doctors who order heart scans, according to results published on August 8 in the Journal of the American College of Cardiology.August 7, 2012Digital X-RayHCA slammed for unnecessary cath proceduresThe largest for-profit hospital chain in the U.S. is under fire for performing thousands of cardiac catheterization procedures that were medically unnecessary, according to an August 6 article in the New York Times.August 6, 2012CTModular training software teaches techs the art of VCA new software-based training tool from the University of Chicago promises to train CT technologists in the complex procedure of virtual colonoscopy -- minus the image interpretation. The tool could help meet training needs should virtual colonoscopy come into widespread use for colorectal cancer screening.August 6, 2012Cardiac ImagingAuntMinnie.com Cardiac Imaging InsiderAugust 5, 2012CTAuntMinnie.com Virtual Colonoscopy InsiderAugust 2, 2012CTJapanese team finds more flat polyps with virtual colonoscopyFlat colorectal lesions aren't easy to detect at virtual colonoscopy. But a group from Japan did quite well finding them after patients underwent bowel cleansing and automated insufflation before CT scanning, according to a new study in Acta Radiologica.July 31, 2012MRIImaging shows how yoga injuries affect tendons, cartilageYoga, that poetic and wildly popular integration of human body, breath, and mind that has swept the U.S. in recent years, does cause musculoskeletal problems, though rarely, according to a new study published in the August American Journal of Roentgenology that used imaging to assess yoga injuries.July 31, 2012Previous PagePage 82 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
