Diagnosis of brain death with technetium 99m hexamethylpropylene amine oxime.
We report on the utility of technetium 99m hexamethylpropylene amine oxime (99mTc-HMPAO) to diagnose brain death following cardiac surgery on a 49-year-old man with triple-vessel coronary artery disease. The imaging parameters and criteria to diagnose irreversible brain damage (brain death) with 99mTc-HMPAO are outlined. Brain imaging with this tracer seems to be more reliable than classic radionuclide angiography and has a potential value to confirm the diagnosis of brain death at an early stage. In addition, it may be used to evaluate the perfusion pattern to other vital organs with potential for transplantation.
