    Journal: Tech Vasc Interv Radiol; 2004 Sep; 7(3):112-22. PubMed ID: 16015555.
    Abstract:
    In this article, we review the many causes of gastrointestinal (GI) bleeding and discuss current strategies for rendering a specific diagnosis. Diagnostic tools considered in this review include: clinical assessment, upper endoscopy, colonoscopy, scintigraphy, and conventional arteriography as well as computed tomography angiography and magnetic resonance angiography. An algorithm for the diagnostic work-up of the patient with GI bleeding is included.
