Duplex ultrasonography is a standard method for screening of carotid disease, and can identify both carotid plaque and stenosis. B-mode ultrasonography combined with color flow imaging is supposed to detect a so-called vulnerable plaque, such as echolucent plaque, plaque with ulceration and mobile plaque. The severity of stenosis can be determined by combining results of peak systolic velocity, end diastolic velocity and pre- and post-stenotic ratios. Although several guidelines have been published, many problems concerning measurements and evaluations of carotid plaque and stenosis remain controversial.
