But in a screening cohort from the Netherlands, polyps and cancer were so common in FOBT patients that VC hardly seemed worth it.July 27, 2008CTCoronary calcium increases mortality risk in elderlyThe presence of coronary artery calcium substantially increases the risk of death among the elderly, a risk that increases with rising calcium burden, according to the first large study aimed at assessing the risk of elderly patients with coronary artery disease.July 22, 2008CTModest mortality gains in CT lung screening modelCT screening for lung cancer may provide a moderate reduction in lung cancer mortality among smokers, according to a study in the July issue of Radiology. The reduction in deaths from all causes due to screening was modest, however, due to competing causes of death among smokers of increasing age.July 21, 2008CTHigher VC laxative dose burdens patients, doesn't improve readsResearchers from the Netherlands report that higher levels of catharsis conferred neither better image quality nor improvement of tagging characteristics on image data, compared to images from subjects given lower laxative doses.July 15, 2008Image ProcessingNew algorithm sharpens coronary artery imagesResearchers at the recent Computer Assisted Radiology and Surgery (CARS) meeting in Barcelona, Spain, presented new work that aims to simplify the difficult task of evaluating coronary artery images.July 13, 2008Cardiac ImagingAuntMinnie.com Cardiac Imaging InsiderJuly 8, 2008Digital X-RayAHA urges cautious use of coronary CTA and MRAA new American Heart Association (AHA) committee statement on the use of coronary CT angiography and MR angiography recommends against screening asymptomatic individuals for coronary artery disease.July 8, 2008CTFourth-generation MDCT scanners do cardiac differentlyOnce upon a time, CT scanners were all pretty similar under the hood, and performance in a given application was predictable across brands. Today's state-of-the-art MDCT scanners take widely divergent approaches to difficult imaging targets and produce different results depending on the application.July 7, 2008AIAll-purpose CAD tool stretches imaging boundariesThe NavI-CAD system discussed by Kensaku Mori, Ph.D., at the 2008 Computer Assisted Radiology and Surgery (CARS) meeting in Barcelona, Spain, is still a work in progress. But a decade of research on the landmark project has yielded a useful set of advanced imaging tools.July 6, 2008Previous PagePage 159 of 258Next PageTop StoriesWomens ImagingBreast imaging reads are shifting from generalists to specialistsSubspecialization may improve patient care, according to researchers.Practice ManagementRadiologists net $824M in industry research paymentsPractice ManagementImaging societies sound off on CMS MPFS final rule for 2026Digital X-RayAI predicts death risk from COPDSponsor ContentClinically Meaningful AI Detection of Interval Cancers
