Cerebral blood flow and cerebral vascular reserve were measured using a stable xenon enhanced computed tomography (Xe-CT) with acetazolamide test. Five normal male adults and ten male patients with occlusive lesion of internal carotid artery were studied. Vascular reserve was 18±13ml/100g/min in the normalcontrol, and 10±10ml/100g/min in the affected side of the patients. Vascular reserve tended to be lower in the affected side than in the normal control. In the patient with “steal phenomenon”, vascular reserve increased after the bypass surgery. Xe-CT with the acetazolamide test is useful to identify candidates for bypass surgery.
