Radionuclide methods of detecting acute gastrointestinal bleeding.
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.
