Regional Cerebral Blood Volume

✓ Forty-five studies of regional cerebral blood volume (rCBV), regional cerebral blood flow (rCBF), and regional cerebral oxygen utilization (rCMRO2) were performed in 30 patients undergoing diagnostic cerebral angiography for evaluation of a subarachnoid hemorrhage due to a ruptured intracranial aneurysm. Tracer methods employing radioactive oxygen-15 were used to measure rCBV, rCBF, and rCMRO2. The patient studies were divided into groups based on their neurological status and the presence or absence of cerebral vasospasm. Subarachnoid hemorrhage, with and without vasospasm, produced significant decreases in CBF and CMRO2. In general, patients with more severe neurological deficits, and patients with more severe degrees of vasospasm, had a more marked depression of CBF and CMRO2. The most striking finding was a significant (p < 0.001) increase in CBV (to 58% above normal) in patients with severe neurological deficits associated with severe cerebral vasospasm. This large increase suggests that cerebral vasospasm consists of constriction of the large, radiographically visible extraparenchymal vessels accompanied by a massive dilation of intraparenchymal vessels.

Dynamic Techniques

A number of different analytical methods were applied to dynamic scans obtained with [18F]2-fluoro-2-deoxy-d-glucose and positron emission tomography. In particular, methods applying three, four, standard, or no rate constants were compared in four studies on three normal subjects. In addition, regional cerebral blood flow, oxygen utilisation, and blood volume were measured using the oxygen-15 steady-state inhalation technique. There was a large difference between values of glucose utilisation obtained with the various analytical methods, in particular between methods using three or four rate constants. This difference was not due to contamination of the tracer with [18F]2-fluoro-2-deoxy-d-mannose. For dynamic techniques, the separate measurement of regional cerebral blood volume was essential. Static techniques (single scans with standard or no rate constants) were best related to dynamic techniques utilising four rate constants. From the results, it followed, however, that these static techniques can only be applied clinically if relatively large disturbances of glucose metabolism and no changes in rate constants are anticipated. The lumped constant was assessed from the combined measurement of oxygen and glucose utilisation and was higher than previously reported.
