[Diagnostic value of dynamic scintigraphy in cases of cerebrovascular disease (author's transl)].
Serial and sequential scintigraphy is amongst the most important noninvasive screening methods for the diagnosis of stenosing or obliterative processes in the carotid territory. In order to check the reliability of the method, the scintigraphic findings in 150 patients were compared with the results of cerebral panarteriography. In the proximal portion (in the neck) there was agreement in 78.7%. Some under-estimation and over-estimation was found in 9% and 8.3%. False positive scintigraphic results were obtained in 2.3%, false negative results in 1.7% of vessels. In the distal territory (carotid syphon/middle cerebral artery) there was agreement in 87.9%. Some over and under estimates occurred in 5.7% and 6.4% respectively. The commonest causes for false positive and false negative results are discussed.
