摘　　要：目的应用超声弹性成像技术评价2型糖尿病(T2DM)患者桡动脉血管壁的弹性变化。方法对T2DM组包括患者37例,正常对照组42名,以常规二维超声测量桡动脉收缩期内径(Ds)和舒张期内径(Dd);应用超声弹性成像技术计算受试者桡动脉内血液与血管壁的应变比值(B/A),并将上述两组受试者各指标进行比较。结果T2DM组桡动脉的应变比值明显高于正常对照组,差异有统计学意义(P<0.05);T2DM组桡动脉舒张期内径及收缩期内径与正常对照组相比差异无统计学意义(P>0.05)。结论超声弹性成像技术可以评价T2DM患者桡动脉血管壁弹性的早期变化。Objective To investigate the elasticity of the radial artery wall in type 2 diabetes mellitus（T2DM） patients with elastosonography.Methods A total of 37 patients with T2DM and 42 normal subjects were studied with elastosonography.The systolic diameter（Ds） and diastolic diameter（Dd） of the radial artery were measured,and the strain ratio of the blood in the radial artery to the wall of the radial artery was calculated.Results The strain ratio of the radial artery in T2DM group was significantly higher than that in normal group（P〈0.05）.There was no significant difference in Ds and Dd of the radial artery between T2DM group and the control group（P〉0.05）.Conclusion The early change of the radial artery wall elasticity in patients with T2DM can be assessed with elastosonography.
