Abstrakt:	The wide availability, speed, safety, and diagnostic accuracy of multidetector computed tomography (MDCT) make it the first-line diagnostic tool in the study of acute bleeding of the lower digestive tract. The use of MDCT after the initial stabilization of the patient makes it possible to identify active bleeding and to determine its origin and possible cause, even when bleeding has stopped. MDCT provides information that is key to selecting the most appropriate treatment option: colonoscopy, embolization, surgery, or clinical follow-up. MDCT orients the surgical or endovascular intervention, minimizing the time, risks, and doses of radiation and of contrast agents involved in the intervention and avoiding "blind" resections associated with greater morbimortality. Although the active presence of radiologists in the Emergency Department involves some disadvantages in scheduling, it also places radiologists in a privileged position in their relations with other techniques and professionals involved in the management of acute lower digestive tract bleeding.
