目的探讨彩色多普勒能量图（CDPI）对早孕不全流产的诊断价值。方法对147例早孕不全流产患者采用二维超声和CDPI观察，用脉冲多普勒（PW）测量病灶内血流参数：血流收缩期峰值速度（PSV）、舒张末期血流速度（EDV）及阻力指数（RI）。结果二维超声于子宫腔内多显示不均匀增强回声灶，边缘不规则。CDPI则显示子宫腔内局灶性血流丰富区，血管盘曲迂回；频谱包络毛糙，呈低阻力动脉型，RI 0.50±0.05。结论CDPI对不全流产具有一定的诊断价值，值得临床应用。

Objective　To study the diagnostic value of color Doppler power imaging (CDPI) for incompleted abortion.Methods　One hundred and forty-seven patients with incompleted abortion were observed by CDPI and B-mode ultrasonography. The blood flow index of peak-systolic velocity (PSV), end-diastolic velocity (EDV) and resistance index (RI) was measured by pulsed Doppler ultrasound.Results　There was a local area of rich blood flow by CDPI in uterine cavity.The spectrum envelope cure was crude and lower resistant , RI 0.50±0.05.Conclusions　CDPI is of certain value to diagnosis of incompleted abortion and is worth while clinical use.
