NeuroradiologyBrain death
irreversible cessation of global brain function that may justify interruption of supportive intensive care measures and eligibility for organ donation.
Electrophysiological studies are complemented by imaging studies: CT and MR show marked homogeneous hypodensity/intensity of the brain tissue but angiography, with demonstration of absent or markedly reduced intracranial arterial flow is considered on a medicolegal basis as a reliable indicator. Scintigraphic perfusion studies using 99m-Tc-HMPAO to demonstrate absent cerebral blood flow are also used.
