AIM: To quantify the volume flow rate- (VFR-) effects of internal carotid disease on the common carotid artery both ipsi- and contralaterally for various degrees of stenosis. METHOD: A non-invasive ultrasonic time domain processing (M-mode) was used.

Since the introduction of transcranial Doppler sonography in the early 1980s, flow velocity estimates have assumed a 0- to 30-degree angle of insonation. Based on limited radiological and anatomical studies, such as assumption appeared justified, and

Color velocity imaging (CVI) is a new non-Doppler ultrasound technique for vascular color flow imaging. Using information contained in the two-dimensional B-mode, gray-scale image to determine velocity, CVI offers potential advantages over Doppler co
