Single-Photon Emission Computed Tomography Enhanced Tc-99m-Pertechnetate Disodium-Labelled Red Blood Cell Scintigraphy in the Localization of Small Intestine Bleeding: A Single-Centre Twelve-Year Study

Abstract

To present our experience with the detection of bleeding in the small intestine by means of scintigraphy with in vivo-labelled red blood cells (RBCs) in the period of 1998-2009. RBC scintigraphy is an effective imaging modality in localizing lower gastrointestinal bleeding in patients for whom other diagnostic tests have failed to locate the bleeding.

RBC scintigraphy can be successful in the detection of bleeding sites in the small intestine.
