The article presents information on the combined whole body positron emission tomography or computed tomography (CT) examination that may be beneficial for staging in patients with colorectal cancer. CT colonography is a recently introduced technique which is being investigated for several indications. Its role as a screening tool for polyp detection is controversial. Studies have shown that the method has a sensitivity in detecting colorectal polyps of 10mm or more in size. But the influence of the scanner or visualization hardware and software is not clear. Despite these concerns, the use of CT or magnetic resonance imaging based colonography in patients with incomplete colonoscopy is becoming more and more accepted examination method in experienced clinical centers.
