CT angiography (CTA) holds promise as an initial test for acute GI bleeding because of its ubiquity, rapidly performance, and potential to offer diagnostic information for management guidance. [62] CTA has the potential advantage of precisely localizing the source of GI bleeding, and to diagnose underlying pathology that may be the cause of bleeding to direct future management. Moreover, CTA can often identify causes of GI bleeding outside the GI tract (eg, hemobilia). In addition, CTA can not only define the underlying vascular anatomy before patients undergo transcatheter angiography embolization but also identify any anatomic variants that may affect management.
