Abstract
The intracarotid injection of radioalbumin microspheres (15 and 30 .mu.m) is followed by scanning procedures that permit the description of the cerebral blood flow distribution. The method is reproducible. Injection can be made into the internal and common carotid arteries, and into the aortic arch or the left ventricle. This last procedure makes it easy to examine patients with severe extracranial vascular stenosis or thrombosis and permits comparison of the 2 hemispheres. Most patients (88%) injected on the affected side showed 1 or more local vascular deficits. The method therefore is more efficient than pertechnetate scanning or arteriography.
