Computerized Ultrasonic Arteriography: A New Technique for Imaging the Carotid Bifurcation

The development of a new noninvasive computerized technique for producing simultaneous lateral, anterior-posterior, and transverse views of the carotid bifurcation for the diagnosis of occlusive disease is described. These multiplanar views have been used to detect 40 percent diameter reductions with a sensitivity of 100 percent and a specificity of 85 percent in 94 comparisons with vessel X-rays.
