摘　　要：血管壁弹性功能改变是动脉粥样硬化等心血管疾病的早期特征,因此早期无创检测血管壁弹性功能受损程度在疾病的防治中具有重大意义。速度向量成像(VVI)技术是新近推出的无创评价心血管壁结构力学与弹性功能的超声新技术,目前在外周动脉中已有较多实验研究。该文就VVI技术评价周围动脉血管壁生物力学状态及弹性功能的临床研究情况予以综述。Functional changes of vascular wall elasticity is the early feature of atherosclerosis and other cardiovascular diseases, Therefore. it is of great significance to detect the elastieity function changes earlier in order to prevent and lreat diseases. Velocity vector imaging（VVI） technique, a novel and noninvasive ultrasound technology,which can evaluate the structural mechanics and elasticity function of heart and vessel wall,is well studied in many experimental studies in peripheral arteries at present. This article reviews the recent advances of VVI in the evaluation of peripheral arteries function.
