方法：对139例卵巢肿瘤患者,其中恶性45例,良性94例,分别经腹及经阴道超声观察二维图像,并进行彩色及频谱多普勒检查,记录阻力指数。
6) Resistance index
阻力指数
1.

2.
Value of preoperative detection of resistance index of lateral thoracic artery and axillary artery in breast cancer by color Doppler sonography
乳腺癌患者术前彩超探查腋动脉和胸外侧动脉阻力指数的研究
3.
Resistance index(RI) and vasculary index(VI) were detected quantitatively.
方法术前应用经阴道彩色多普勒超声(Transvaginal color doppler ultrasonography,TVCDU)与三维彩色血管能量成像(Three-d imensional color power an-giography,TR3D-CPA)检测38例卵巢恶性肿瘤患者,测定肿瘤血流阻力指数(Resistance index,R I)与血管指数(Vasculary index,VI),分析R I、VI与临床分期的关系。
补充资料：肺循环阻力(或全肺阻力)
肺循环阻力(或全肺阻力)
pulmonary circulation resistance
血液在肺部血管内流动时和血管壁之间的摩擦力和血液内部的摩擦阻力。肺动脉管壁较薄，分支短而管径大，故肺动脉的可扩性较大，对血流的阻力很小，仅0.12PRU(外周阻力单位)。肺循环动脉部分总的阻力和静脉部分总的阻力相等，故血液流动时在动脉部分的压力降落和静脉部分的压力降落相等。
