May 15, 2007 — Computed tomography (CT) colonography, also known as a virtual colonoscopy (VC), has been found to have a high concordance with optical colonoscopy in identifying significant polyps.

Initial CTC screening performed as well as universal colonoscopy in the detection of advanced neoplasia — and minimized the risk for perforation. In earlier studies, the accuracy of computed ...

» How is CT colonography performed? CT colonography takes about 15 minutes. At the beginning of the procedure, the colon is filled with carbon dioxide or air with a tube introduced into the rectum.

Study: Gastroenterologists’ Readings of CT Colonoscopy Close to Radiologists’ A study published in a recent issue of Endoscopy showed that gastroenterologists trained in reading computed tomography ...

CT scans can detect about 90% of the medium and large lesions and cancers detected by colonoscopy, a study in this week's New England Journal of Medicine found. The finding suggests that people who ...

CT colonography (CTC) screening, in which diminutive polyps detected are not reported or removed, has been suggested as a selective filter for therapeutic optical colonoscopy (OC) in the detection of ...

Although medical literature has shown computerized tomographic colonography and optical colonoscopy are both effective at detecting advanced adenomas, recent research indicates optical colonoscopy ...

A study by researchers at UCSF Medical Center has found that virtual colonoscopy may not measure up to conventional colonoscopy for widespread colorectal cancer screening in the U.S. Using a “decision ...
