Confirmation of brain death using 99m Tc HM-PAO.

Because 99m Tc HM-PAO is simple to use, noninvasive and readily available, it appears to satisfy most criteria for the use of radionuclide cerebral imaging in the confirmation of brain death. Waiting periods, which are often included in brain death protocols, delay the diagnosis of brain death. 99m Tc HM-PAO has proven to be a useful test to confirm brain death.
