title: Brain death: confirmation by radionuclide cerebral angiography.
abstract: Dynamic radionuclide cerebral angiography was performed in 14 patients with suspected brain death. In 10 of 14 patients, no intracranial arterial perfusion was demonstrable, thus confirming brain death. In four patients, faint venous activity was seen in the sagittal sinus only. All these patients also eventually died. Radionuclide cerebral angiography provides a simple and noninvasive means to confirm brain death in critically ill patients maintained on life support systems particularly when an electroencephalogram and four vessel contrast angiography may be either impractical or equivocal.
