报告了应用彩色多普勒超声对50例糖尿病患者的下肢动脉病变的研究。结果显示糖尿病组下肢动脉内径、血流量低于正常组（P＜0．01），加速度／减速度比值及血流峰值速度高于正常组（P＜0．001）。彩色多普勒超声可定量估价糖尿病下肢动脉功能、病变部位和程度。
Reported the application of color Doppler ultrasound in 50 patients with diabetic lower extremity arterial lesions. The results showed that the arterial diameter and blood flow of lower extremities in diabetic group were lower than those in normal group (P <0.01). The acceleration / deceleration ratio and peak blood flow velocity were higher in diabetic group than in normal group (P <0.001). Color Doppler ultrasound quantitative assessment of lower extremity arterial function of diabetes, lesion location and extent.
