CT colonographic technique continues to evolve as advances in helical CT and computer technology are made. The performance of CT colonography is dependent on patient preparation, state-of-the-art equipment, and properly trained radiologists who are familiar with interpretation of CT colonographic findings. Although multiple studies have shown that CT colonography has excellent sensitivity and specificity in the detection of large polyps in high-risk or symptomatic patients, we cannot extrapolate this experience to a screening population until confirmatory studies have been performed.
