Lesion size and morphology at VC good predictors of histology
Size and morphology are good predictors of whether a colorectal lesion harbors advanced histology and needs to be removed, according to a new multicenter study from Italy. The results suggest that polyps of the same size detected at virtual colonoscopy could be classified and managed differently based on their morphology.

CAD catches most flat polyps on virtual colonoscopy
Computer-aided detection (CAD) is sensitive for all but the flattest of flat colorectal lesions, even in minimally prepped patients, according to a new study from Italy. Using CAD, radiologists significantly improved their ability to detect the elusive polyps, which can harbor precancerous lesions.

Studies spotlight high CT radiation dose, increased cancer risk
Two studies appearing in this week's Archives of Internal Medicine reveal higher-than-expected radiation dose in clinical CT studies and increased lifetime potential cancer risks as a result. At a minimum, the U.S.-funded studies suggest that dose-reduction efforts have not spread widely enough across the U.S.

ASIR cuts dose in Crohn's disease patients
CHICAGO - Low-dose abdominal CT images reconstructed with an adaptive statistical iterative reconstruction (ASIR) technique are equivalent -- and, in fact, slightly better in quality -- than standard-dose images reconstructed with filtered back projection.

Contrast dose halved in coronary CTA
CHICAGO - Contrast doses for CT angiography (CTA) are too high, but they can be lowered substantially with the right equipment and careful attention to technique, according to researchers from Charité University Medical School in Berlin.
