Carotid angiography in conjunction with amytal testing of epilepsy patients

Angiography is carried out as a basic part of the sodium amobarbital procedure in most institutions in order to predict the distribution of the amobarbital before the procedure itself is performed. This paper presents details of cerebral circulation to provide a framework that will help investigators who are not radiologists to interpret angiography results. The application of angiography specifically to the amobarbital procedure and the implications of different patterns of arterial filling for interpretation of speech and memory test results are discussed.
