BRAIN DEATH: RAPID EVALUATION USING COMPUTERIZED RADIONUCLIDE CEREBRAL
1986
SUMMARY Demonstration of arrested intracerebral blood flow is the ultimate evidence of brain death. Computerized radionuclide cerebral flow study was done on 18 patients diagnosed clinically as brain dead. Correlation was made with clinical neurophysiological and EEG findings. The criteria for diagnosis of arrested intracerebral perfusion using radionuclide flow study were: non-visualiza tion of blood flow activity in the intracranial arteries during the arterial phase,diffused cerebral activity during the capillary phase and non-filling of venous sinuses during the venous phase;visuali zation of typical 'hot nasal' activity; the time
