Ever since transplant surgery became a common procedure. The early diagnosis of irreversible cessation of cerebral function has become an important need We analysed the findings of transcranial doppler of five cases. Two was diagnosed brain death by currently accepted criteria. Two cases showed absence of intracranial blood flow and normal to disturbed flow status of the cervical carotid artery. Three cases showed reverberating flow pattern with reflux phenomenon. Transcranial doppler investigation seems to provide a practical, non-invasive. And reliable disgnostic evidence for the arrest of cerebral circulation.

Hemimasticatory spasm is a rare disorder that often accompanies facial hemiatrophy and is characterized by spasm in one or more of the jaw-closing muslces supplied by the fifth cranial nerve. We report a clinical and electrophysiological observation of a patient of hemimasticatory spasm, who presented involuntary spasm on masseter muscle and hemiatrophy of the face on the right side for 7 years.

The confirmatory diagnosis of Moyamoya disease has been obtained by invasive angiographic examination. We report the results of MRI and transcranial doppler sonography of three cases ol Moyamoya disease, which ws disgnosed by clinical and angiography. We think that the diagnosis of Moyamoya disease can be made by noninvasive MRI and transcranial doppler sonography without conventional invasive angiography.
