Value of contrast-enhanced CT in detecting active hemorrhage in patients with blunt abdominal or pelvic trauma.

Abstract

Active extravasation of contrast material (representing bleeding) can be detected in trauma patients who are physiologically stable enough to undergo CT of the abdomen or pelvis. Extravasated contrast material can be distinguished from clotted blood by measuring CT attenuation. CT accurately shows the anatomic location of bleeding and indicates the probable vascular origin. CT, therefore, can be used as a guide for angiographic or surgical intervention.
