Comparison of CT colonography and flexible colonoscopy, initial experiences with 128 slice CT

Background and aims: CT colonography (CTC) is a relative novel, minimal invasive method for visualization of the large bowel. The use of CTC allows virtual endoscopy of the whole colon in most patients. Recently we have the opportunity in our hospital to perform CTC with a new 128 slice CT. The aim of our work was to compare CTC results with flexible colonoscopy findings and to demonstrate with case presentations the advantages and limitations of CTC in the diagnosis of colorectal polyps, cancers and diverticulosis. Methods: We performed a prospective comparative pilot study with CTC and flexible colonoscopy. Th…
