但肝硬化腹水组肾动脉阻力指数（RI）和搏动指数（PI）均显著高于其余两组（P<0.01）。

But resistive index (RI) and pulsatile index (PI) were markedly higher in cirrhotic patients with ascites than that in cirrhotic patients without ascites and that in the control group (P<0.01).

采用彩色多普勒血流成像，以肾动脉阻力指数(RI)为参数，对犬肾移植动物模型的急性排斥反应进行检测。

In this study, CDFI has monitored for acute renal transplant rejection according to the increased renal artery resistance index (RI).

肾动脉流速、流量及其阻力指数与正常人比较无统计学意义（P＞0．05）。

Renal artery velocity, volume and RI had also no difference( P >0 05).
