title: Doppler ultrasound scanning of the carotid bifurcation.
abstract: The results of Doppler scanning of 146 carotid bifurcations in 86 patients were correlated with carotid arteriography. The correlations for normal carotid arteries ranged from 63% to 98%; the correlation for occlusions of carotid arteries was 100%. The Doppler scan correlated in 70% to 85% of stenoses of the internal or external carotid arteries near their origins. The technique may be performed by a well-trained technician or physician.
