Demonstration of bleeding site by 99mTc-labeled red cells.
Radionuclide angiography using in vivo 99mTc-tagged red cells demonstrated different bleeding sites in one patient on three occasions. The study is easy to perform and may be more sensitive than contrast angiography in the presence of slow bleeding.
