title: Computed tomography evaluation of gastrointestinal bleeding and acute mesenteric ischemia.
abstract: Gastrointestinal bleeding and acute mesenteric ischemia are conditions that generally require an urgent and accurate diagnosis. In this setting, multidetector computed tomography (MDCT) can play an important role. This article discusses current techniques, the findings in correlation with pathophysiology, and the proper use of MDCT in the diagnostic evaluation and management of these patients.
