| 摘 要： | 速度向量成像(VVI)技术是新近发展起来的一种无创、定性、定量评价血管壁运动及弹性功能的超声技术,能直观、准确地评价管壁运动力学特征,灵敏地反映颈动脉粥样硬化早期血管壁弹性及运动特征的改变;观测动脉粥样硬化斑块在血管壁运动时受力及旋转情况,为研究动脉斑块的不稳定性提供新的方法.VVI在研究机体其他部位血管的运动力学特征亦有报道.本文对VVI技术在血管方面的研究应用现状加以综述.

| 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 ... |
