Abstract:
Velocity vector imaging (VVI) is a promising and relatively new noninvasive method of assessing wall movement and flexible features of vessels,being able to qualitatively, quantitatively, accurately and intuitively assess mechanical characteristics of vascular wall movement. VVI can reflect changes of characteristics of flexibility and movement of carotid artery in early atherosclerosis and plaque rotation angle. It provides a new way for the study of unstable plaque. The research and current status of clinical application of VVI were reviewed in this article.
