Resistive Index RI 阻力指数
Lesion vascularity, pulsatility index (PI), and resistive index (ri) of the vessels detected were analyzed. And correlated with histologic results.
分析病变处血流的搏动指数(PI)和阻力指数(R I)与病理组织学结果的关系。
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).
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)。
Conclusion ri may play no role in the differential diagnosis for unilateral upper urinary hydrocele. Resistive index ratio may contribute to it.
结论阻力指数鉴别单侧梗阻性和非梗阻性上尿路积水的能力可能有限,阻力指数率可能有助于单侧上尿路积水的鉴别。
