Intra-arterial contrast-enhanced spiral CT: adjunct to angiography for localizing obscure gastrointestinal bleed.

We report two patients with obscure GI bleed in whom we performed intra-arterial contrast-enhanced spiral CT scan of abdomen with the angiography catheter in the superior mesenteric artery (SMA). The technique localized the lesions to the mid jejunum and distal duodenum.
