Computed tomography as an angiographic aid in evaluation of intraabdominal hemorrhage

The role of computed tomography in the evaluation of patients with intraabdominal hemorrhage in the absence of trauma history has received little attention. Representative cases are presented demonstrating how preangiographic, postangiographic, and combined computed tomography-angiography can aid in the diagnosis and localization of obscure causes of intraabdominal and gastrointestinal bleeding.
