title: Computed tomography of the rectum with water as contrast agent.
abstract: The use of intrarectally administered plain tap water as a contrast medium for CT scan of the rectum and sigmoid combined with iv iodine contrast medium was prospectively studied in 28 patients. This method allowed correct demonstration of mural wall abnormalities in all patients and therefore represents a simple, inexpensive, and efficient modality for CT study of the rectum and sigmoid.
