目的：探讨速度向量成像（VVI）技术评估初诊2型糖尿病患者颈总动脉（CCA）管壁运动的意义。方法选取30名初诊2型糖尿病患者（糖尿病组）和30例健康正常人（对照组）；常规二维超声观测CCA的内径、IMT及斑块情况；采用VVI技术对受检者行颈动脉超声检查，测得并记录右侧CCA管壁短轴方向二维图像前壁、前内侧壁、后内侧壁、后壁、后外侧壁、前外侧壁6个节段的径向最大速度（Vs）、切向最大应变（Smax）及切向最大应变率（SRmax），对各组相关参数进行统计学分析。结果糖尿病组IMT厚度显著高于对照组（P＜0．05）；糖尿病组及对照组颈总动脉内径测值无明显统计学差异（P＞0．05）。糖尿病组患者CCA6个节段的Vs、Smax和SRmax均显著低于对照组（ P＜0．05）。结论 VVI技术可用于评价初诊2型糖尿病患者颈总动脉管壁运动的协调性，可以评估动脉的弹性状况。

Objective To discuss the value of velocity vector imaging ( VVI) in the assessment of the common carotid artery wall motion in patients with newly diabetes .Methods All subjects were assigned into T2DM group of 30 patients and the normal control group of 30 cases.Two-dimensional dynamic images of the common carotid artery were obtained .The internal diameter,IMT and carotid athero-sclerotic plaque during its expansion were measured .Then the peak systolic velocity(Vs),strain(Smax) and strain rate(SRmax) of the six segments of the common carotid artery wall ( anterior wall ,posterior wall ,anterolateral wall ,anterointernal wall ,posterolateral wall and posterointernal wall ) were analyzed quantitatively and compared mutually by VVI technique .Results IMT of T2DM group was signifi-cantly thicker than that of control group (P <0.05).There was no statistically significant difference between the internal diameter of T2DM group and control group(P>0.05).The Vs,Smax and SRmaxof T2DM group was significantly lower than that of control group (P<0.05).Conclusions VVI technique is an effective method of quantitatively assessing the common carotid arterial elasticity of pa -tients with newly diagnosed diabetic mellitus .
