Quantified analysis of a carotid angiogram.

To compensate for differences in anatomy and magnification, a hand-held programmable calculator remodels the profile of the lateral view of a skull to fit the outline of a reference skull. The statistical analysis of 85 normalized carotid angiograms yeilds a numbered map of supratentorial structures. It is then possible to obtain, within 20 min and without sophisticated equipment, an objective analysis of any new angiogram.

Use of 99mTc-labeled albumin microspheres in cerebral vascular disease.

The intracarotid injection of radioalbumin microspheres (15 and 30 mum) is followed by scanning procedures that permit the description of the cerebral bloodflow distribution. The method is reproducible. Injection can be made into the internal and common carotid arteries, as well as 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 two hemispheres. Most patients (88%) injected on the affected side showed one or more local vascular deficits. The method therefore is more efficient than pertechnetate scanning or arteriography.

Study in cerebrovascular disease: brain scanning with technetium 99m pertechnetate; clinical correlations.

A prospective brain scanning study using technetium 99m pertechnetate was performed in 84 patients with cerebral infarction. No correlation was found between vascular angiographic findings and the frequency of positive scans. A comparison with clinical motor and mental evaluation showed a good correlation between abnormal scans (58 percent) and poor initial test resutls. A half-life of 17 days characterized the time course of positive scans according to their density and abnormal radioisotopic uptake area.
