Diagnostic Modalities in Gastrointestinal Bleeding

Abstract: A variety of diagnostic modalities is available to assist in the evaluation of patients presenting with acute gastrointestinal (GI) bleeding. This article reviews some older technologies like colonoscopy, nuclear scintigraphy, and conventional angiography and will also review the newest additions to the lower GI bleeding diagnostic toolbox, which are video capsule endoscopy and computed tomography (CT) angiography.
