VC CAD aids experts in detecting intermediate polyps

Computer-aided detection (CAD) can improve the performance of experienced radiologists in detecting intermediate-sized (6- to 9-mm) polyps, but it doesn't help find larger lesions, said researchers from Italy in results presented at the RSNA meeting earlier this month.

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.

Surveillance polyps show little growth at follow-up

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

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.

CAD fails to make up for inexperience in reading VC studies

By Erik L. Ridley

Using computer-aided detection (CAD) software with a 3D display technique can increase sensitivity for inexperienced readers of virtual colonoscopy exams, but it fails to narrow the performance gap with experienced interpreters, according to a study published in the October issue of Clinical Radiology.

VC excels at diverticulosis staging

Although virtual colonoscopy practice has always focused on adenoma detection and colon cancer prevention, the exam is proving to be formidable in the staging of diverticular disease, a scourge of fast-food Western nations that affects most of their citizens by age 60.

Colon cancer screening likely to become cost-saving as chemotherapy costs rise

By Reuters Health

NEW YORK (Reuters Health), Sep 25 - As chemotherapy costs rise, it is likely that most colorectal cancer screening strategies will become not just cost-effective, but also cost-saving, according to a report in the September 24 online issue of the Journal of the National Cancer Institute.

Aspirin fights colon cancer risk of gene disorder

By Reuters Health

BERLIN (Reuters), Sep 22 - A daily dose of aspirin can prevent cancer in people with a genetic disorder that increases their risk of developing the disease, scientists said on Monday.

VC researchers weigh 3 iodine tagging regimens

A laxative-and-tagging regimen consisting of iodinated contrast plus a sodium phosphate mixture showed the best cleansing results among three concoctions in preparing for virtual colonoscopy exams. But a two-day regimen of iodinated contrast and a mild laxative at mealtime was better accepted by patients, according to a new study from Italy.
