ABSTRACT

A comparison between radiocontrast and radionuclide angiography was made in 272 patients with cerebrovascular disease. The radionuclide studies showed a 58% true-positive rate and 11% false-positive rate. The true-positive rate for patients with unilateral carotid artery disease was 66%. These results were similar to those of other reported series (63% true positive and 11% false positive). Therefore, radionuclide angiography is not recommended as the major screening procedure in cerebrovascular disease.
