Ever since transplant surgery became a common procedure, the early diagnosis of irreversible cessation of cerebral function has become an important need. We made a comparative study of EEG, angiography and transcranial Doppler imaging in patients who fulfilled the clinical criteria for brain death. The imaging was performed with a 2 MHz pulsed Doppler system with a unique transcranial probe (EME, type TC2-64 B). Intracranial reverberating flow patterns with counterbalancing forward and backward components of the blood column indicate flow arrest. Transcranial Doppler Sonography was found to be a practical, non invasive, early and reliable method for the diagnosis of arrest of the cerebral circulation.

D001926	Brain Death	A state of prolonged irreversible cessation of all brain activity, including lower brain stem function with the complete absence of voluntary movements, responses to stimuli, brain stem reflexes, and spontaneous respirations. Reversible conditions which mimic this clinical state (e.g., sedative overdose, hypothermia, etc.) are excluded prior to making the determination of brain death.
