Angiography in lesions of the small bowel.
Following the introduction of endoscopy and newer imaging techniques, such as ultrasonography, computer tomography and magnetic resonance imaging, the indications for angiography have been reduced mainly to the diagnosis and treatment of unexplained gastrointestinal hemorrhage and ischemia. Radiologic signs of hemorrhage include extravasations of contrast medium, irregular vessels and aneurysms. Vascular stenoses and occlusions are the main radiologic signs of ischemia.
