摘要：Pulse-wave velocity (PWV) is typically used for estimating the stiffness of arteries This study was to implement a new method and rapid two-dimensional ultrasound method for the measurement of PWV in the carotid artery. The longitudinal dynamic image of CCA was analyzed using syngo Velocity Vector Imaging technology. Due to the propagation of pulse wave, nearby different sampling point will have same curves after the transit time between those sampling point. The regional PWV was calculated according to the formula and be applied for the measurement of the other vascular arteries. The noninvasive imaging method for calculating the regional PWV may contribute to a good alternative screening test in the evaluation of cardiovascular diseases and reduce the overall morbidity and mortality of cardiovascular diseases. In summary, our results demonstrate that velocity vector imaging can be an effective and promising approach for evaluate pulse wave velocity of the carotid artery.
