We have been using a high resolution real time ultrasound mechanical sector scanner to visualize the carotid bifurcation. Twenty-six patients were studied before carotid arteriography for transient ischemic attacks. One bifurcation was not adequately visualized. Of the remaining 51, plaques were identified correctly in 29; absence of plaques was identified correctly in 15; small plaques were demonstrated by ultrasound in two that did not appear on the arteriogram; and four small plaques and one significant stenosis were not identified by ultrasound.
