title: Radionuclide methods of detecting acute gastrointestinal bleeding.
abstract: It is clinically very important to localize the bleeding site in suspected patients. Current common diagnostic methods are endoscopic, angiographic, and radionuclidic. Of the noninvasive procedures, 99mTc-RBC and 99mTc-colloid methods have gained wide popularity. In our series of a comparative study, the RBC method has been shown to be more accurate than the colloid method. The 99mTc-RBC method should be available as a routine emergency procedure in every large clinical center.
