目的：探讨速度向量成像（velocity vector imaging ，VVI）技术评价初诊2型糖尿病患者颈总动脉（common carotid artery ，CCA）弹性的应用价值。方法：选取60例初诊2型糖尿病患者，将其分为内中膜厚度（intima-media thickness ，IMT）增加组（T2DM-1组）30例和IM T正常组（T2DM-2组）30例；另选取健康对照组30例。常规二维超声观测糖尿病患者与健康对照组的CCA内径、IM T及斑块情况；采用VVI技术对受检者行颈动脉超声检查，测量并记录右侧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：T2DM-1组 IMT 厚度显著高于 T2DM-2组和对照组（P＜0.05）；T2DM-2组IMT厚度与对照组差异无统计学意义（P＞0.05）；T2DM-1组、T2DM-2组及对照组CCA内径测值差异无统计学意义（P＞0.05）。T2DM-1组患者CCA 6个节段的Vs、Smax和SRmax显著低于 T2DM-2组和对照组（P＜0.05）；T2DM-2组患者CCA 6个节段的Vs、Smax和SRmax显著低于对照组（P＜0.05）。结论：初诊2型糖尿病患者CCA二维形态未改变以前CCA弹性已经降低，VVI技术可用于评价CCA的弹性状态，能够早期发现初诊T2DM患者的CCA弹性降低。
目的：探討速度嚮量成像（velocity vector imaging ，VVI）技術評價初診2型糖尿病患者頸總動脈（common carotid artery ，CCA）彈性的應用價值。方法：選取60例初診2型糖尿病患者，將其分為內中膜厚度（intima-media thickness ，IMT）增加組（T2DM-1組）30例和IM T正常組（T2DM-2組）30例；另選取健康對照組30例。常規二維超聲觀測糖尿病患者與健康對照組的CCA內徑、IM T及斑塊情況；採用VVI技術對受檢者行頸動脈超聲檢查，測量併記錄右側CCA管壁短軸方嚮二維圖像前壁、前內側壁、後內側壁、後壁、後外側壁、前外側壁6箇節段的徑嚮最大速度（Vs）、切嚮最大應變（Smax）及切嚮最大應變率（SRmax），對各組相關參數進行統計學分析。結果：T2DM-1組 IMT 厚度顯著高于 T2DM-2組和對照組（P＜0.05）；T2DM-2組IMT厚度與對照組差異無統計學意義（P＞0.05）；T2DM-1組、T2DM-2組及對照組CCA內徑測值差異無統計學意義（P＞0.05）。T2DM-1組患者CCA 6箇節段的Vs、Smax和SRmax顯著低于 T2DM-2組和對照組（P＜0.05）；T2DM-2組患者CCA 6箇節段的Vs、Smax和SRmax顯著低于對照組（P＜0.05）。結論：初診2型糖尿病患者CCA二維形態未改變以前CCA彈性已經降低，VVI技術可用于評價CCA的彈性狀態，能夠早期髮現初診T2DM患者的CCA彈性降低。

Objective:To investigate the application value of velocity vector imaging (VVI) in assessing the elastic change of common carotid artery in patients with newly diabetes .Methods :All subjects were divided into T2DM-1 group of 30 patients with thicker IMT ,T2DM-2 group of 30 patients with normal IMT 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 atherosclerotic plaque dur-ing its expansion were measured .Then the peak systolic velocity (Vs) ,strain(Smax) and strain rate(SRmax) of the six seg-ments 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-1 group was significantly higher(P<0 .05) than that of T2DM-2 group and control group .There was no statistically significant difference between IMT of T2DM-2 group and control group(P> 0 .05) .There was no statistically significant difference be-tween the internal diameter of T2DM-2 group and control group(P>0 .05) .The Vs ,Smax and SRmax of T2DM-1 group was lower significantly(P<0 .05) than that of T2DM-2 group and control group .The Vs ,Smax and SRmax of T2DM-2 group was lower significantly(P<0 .05) than that of control group .Conclusions :The CCA elasticity of patients with newly diagnosed dia-betic mellitus decreases before the morphological indicators change .VVI technique is an effective method of quantitatively asses-sing the carotid arterial elasticity .
