Computed tomography colonography (CTC) is a recently developed technique for colonic and rectal diseases. After using the multi-slice spiral CT (MSCT) to rapidly scan the aerated colon and rectum, the original images are post-processed using advanced imaging software to acquire a series of reconstruction images. Possessing the advantages of simpleness, rapidness, safety and noninvasiveness, CTC is more easily accepted by patients. As MSCT technology and computed software are constantly being improved, the image quality and diagnostic reliability of CTC have been enhanced greatly. CTC not only has high sensitivity and specificity for detecting polyps over one centimeter but also shows clear advantage in accurate preoperative diagnosis and staging of colorectal carcinoma.
