Lesion size and morphology at VC good predictors of histology

By Eric Barnes

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

By Eric Barnes

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.

Chest x-ray CAD fails to boost observer performance

By Erik L. Ridley

CHICAGO - Computer-aided detection (CAD) software may not produce significant improvement in detecting suspicious lesions on chest radiographs, but it's not necessarily the technology's fault, according to research presented Wednesday at the 2009 RSNA meeting in Chicago.

Surveillance polyps show little growth at follow-up

By Eric Barnes

CHICAGO - A preliminary study from Italy adds weight to the argument that two- to three-year surveillance of 6- to 9-mm polyps doesn't unduly increase the risk of colorectal cancers. Diminutive polyps grow faster but present less cause for concern.

Wireless capsule endoscopy feasible in young children

By Reuters Health

NEW YORK (Reuters Health), Nov 11 - Wireless capsule endoscopy is feasible for detecting small intestinal pathology in children younger than 8 years old, according to a report in the November Gut. However, most children in this age group are unable to swallow the small device, so it needs to be introduced endoscopically.

Meta-analysis reveals paucity of advanced neoplasia in small polyps

By Eric Barnes

The prevalence of advanced neoplasia in subcentimeter polyps is extremely rare, according to a new meta-analysis of virtual colonoscopy data from more than 20,000 patients. As a result, the study authors believe that it's unnecessary to incur the costs and risks associated with resecting diminutive colorectal lesions detected at VC.
