  • Abstract
  • Look Inside

 We report the successful CT imaging of virtual endoscopy and CT enema in a patient with obstructive sigmoid colon cancer and multiple colon polyps, using multidetector-row CT. The three-dimensional (3D) images were compatible with intraoperative colonoscopic findings and the gross appearance of the resected specimen. It was also possible to make images of the proximal side of the obstructive colon cancer. Although bowel preparation and a spatial resolution can be a problem, the images visualized by 3D-CT are unique, and images of CT enema are similar to those of barium enema study. Additionally, virtual endoscopy can help us understand the whole image of a lesion. We think 3D-CT will become one of the new modalities for investigating colorectal cancer in addition to colonoscopy and barium enema study.
