Abnormal Gastrointestinal Accumulation of Radiotracer by Gastric Bleeding During 99mTc-MDP Bone Scintigraphy / 대한핵의학회잡지

ABSTRACT

We present a case in which a patient with acute hemorrhagic gastritis demonstrated abnormal gastrointestinal accumulation of radiotracer during Tc-99m-methylene diphosphonate (MDP) skeletal scintigraphy. A hemorrhage gastritis was subsequsently demonstrated by endoscopy. The menchanism for the intestinal localization of Tc-99m-MDP in this patient is not clear, but we guess that the extravasated blood containing the radiopharmaceutical cannot recirculate and stays at the bleedings site, so we can see the intestinal activity.
