How Does CT Colonography Compare to Other Screening Methods?
CT Colonography is one of several screening methods for colorectal cancer, including conventional colonoscopy, fecal occult blood tests (FOBT), and flexible sigmoidoscopy. Each method has its advantages and limitations. For instance, conventional colonoscopy allows for direct visualization and removal of polyps during the same procedure, while FOBT is non-invasive and does not require bowel preparation. The choice of screening method should be based on individual risk factors, preferences, and medical history.
