Computed tomography colonography (CTC) is a minimally invasive, fast, safe and accurate screening examination for colorectal cancer. It also allows evaluation of structures outside the colon. A successful CTC examination requires good bowel preparation, adequate patient hydration, tagging agents, the use of automated carbon dioxide insufflation, and correct positioning for two view and additional view scans. Knowledge of polyp morphology and measurement of polyps are important when interpreting 2D or 3D scans.
