Demonstrating absence of cerebral blood flow

Absence of cerebral blood flow may also be used to confirm death of the whole brain. Four-vessel cerebral angiography was used in the past, but radionuclide cerebral scanning, which cannot document absent flow in the vertebrobasilar circulation, has been introduced more recently. Color flow duplex scanning may be used to complement radionuclide cerebral scanning. Although total absence of cerebral blood flow provides compelling evidence of brain death, findings can be equivocal in the presence of unequivocal clinical signs of brain death.
