Doppler ultrasound evaluation of extracranial cerebrovascular disease.
Carotid Doppler examination was compared with arteriographic findings in 125 patients. The results demonstrated exact correlation in 87% of vessels studied. Clinically significant errors occurred at a rate of 4.5%. Clinically insignificant errors (8.5%) were usually the result of wall disease being mistaken for nonhemodynamically significant stenosis.
