The detection and location of gastrointestinal (GI) bleeding has become an important part of routine nuclear medicine practice. This study must be understood, done well, and read skillfully in order to provide a service to the referring physician. Much of the confusion over the reading of these scans can be readily explained as a failure to follow the rules of interpretation. Many of the published “pitfalls” are really examples of abnormal findings or normal variants that can be readily separated from the studies that successfully localize hemorrhage.1 It is also important to point out that scintigraphy is not done to determine that there is hemorrhage. That much is usually known at the start. No one needs a “nuclear guaiac.” Localization of the site of hemorrhage is paramount in guiding further evaluation and therapy. This discussion will explain the technique and interpretation of red blood cell (RBC) GI bleeding study.
