The diagnostic accuracy of Doppler ultrasound examination of the vertebrobasilar system has been reported to be lower than that of examinations of the carotid system. However, with the introduction of color Doppler flow imaging, the diagnostic power in this territory may be increased. 1 Most studies have dealt with normal subjects, used color Doppler flow imaging without additional ultrasound methods, and have not used intraarterial angiography as a control. 1–3 Studies comparing a combination of the different available ultrasound systems in examinations of patients with pathologic changes in the vertebrobasilar system with intraarterial angiography have yet to be performed. Accordingly we have combined continuous‐wave Doppler, color Doppler flow, and transcranial Doppler of the vertebrobasilar territory to determine their sensitivity and specificity in comparison with intraarterial angiography in the detection of obstructive lesions.
