Helical CT scanning of the abdomen and pelvis is recommended when a routine workup fails to determine the cause of active gastrointestinal bleeding. Findings of helical CT scan in lower gastrointestinal bleeding include vascular extravasation of the contrast medium, contrast enhancement of the bowel wall, thickening of the bowel wall, hyperdensity of the peri-bowel fat, and vascular dilatations.
