Answer

Helical computed tomography (CT) scanning of the abdomen and pelvis can be used when a routine workup fails to determine the cause of active GI bleeding. Multiple criteria are used for establishing the bleeding site, including the following [1, 2] :

  • Vascular extravasation of the contrast medium

  • Contrast enhancement of the bowel wall

  • Thickening of the bowel wall

  • Spontaneous hyperdensity of the peri-intestinal fat

  • Vascular dilatations
