title: Acute gastrointestinal bleeding: CT angiography with multi-planar reformatting.
abstract: Acute gastrointestinal bleeding is a common medical emergency, which carries a significant mortality. CT Angiography is an important non-invasive diagnostic tool, which can be used to plan subsequent endovascular or surgical management. The cases presented demonstrate that a meticulous and systematic approach to image interpretation is necessary, in particular, to detect focal sites of contrast extravasation and small pseudoaneurysms.
