Question

Quizplus · Accepted Answer

Localization of acute gastrointestinal bleeding is best accomplished with nuclear medicine, specifically with a procedure called technetium-99m-labeled red blood cell scintigraphy. This test involves injecting a small amount of radioactive material into the patient's bloodstream, which will then be detected by a special camera that can locate the site of bleeding. CT, ultrasonography, and laparoscopy may also be used to evaluate gastrointestinal bleeding, but they are not considered the best options for initial localization.
