Air insufflation of the colon as an adjunct to computed tomography of the pelvis.

Air insufflation of the colon as an adjunct to pelvic CT examinations was performed in 49 patients for evaluation of a known or suspected pelvic mass or in follow-up of treated pelvic tumors. This safe, simple method of colonic visualization clearly outlines the rectosigmoid colon and permits a reliable assessment of the mucosa, wall thickness, and extrinsic abnormalities, thereby improving diagnostic accuracy in staging pelvic malignancy and evaluating pelvic pathology.
