Scintigraphy of patient with hematochezia.
Gastrointestinal bleeding can result in significant morbidity. Scintigraphy plays an important role in detecting, localizing, and grading the bleed. Effective scintigraphic evaluation of gastrointestinal bleeding can be complicated by its intermittent nature and the patient's hemodynamic instability. Dynamic evaluation, delayed imaging, and an understanding of the labeling process are necessary tools to help improve detection rate and localization.
