Improving predictive value of complementary tests in carotid artery disease.

ABSTRACT

In a prospective study the accuracy of B-mode ultrasound imaging alone was compared with its use in conjunction with bidirectional Doppler ultrasound, carotid phonoangiography, and oculoplethysmography to independently assess contrast arteriograms of carotid arteries studied for presumed extracranial vascular disease. The addition of B-mode real-time imaging improved the accuracy of diagnosis by nearly 10%.
