We investigated the validity of the flow parameter minimal resistance index (min RI) for discrimination of breast tumours. Colour and spectral Doppler sonography was performed on 114 patients. An increase in number of tumour vessels was paralleled by a significant drop of the minimal (min) RI (p=0.004) and increase of the maximal (max) RI (p=0.03) while mean RI was not influenced. The present results question the validity of min RI as parameter for discrimination of breast tumours. Min RI does not represent the actual flow resistance.
我们研究了血流参数最小阻力指数（min RI）在鉴别乳腺肿瘤方面的有效性。对114例患者进行了彩色及频谱多普勒超声检查。肿瘤血管数量增加的同时，最小阻力指数（min RI）显著下降（p = 0.004），最大阻力指数（max RI）增加（p = 0.03），而平均阻力指数不受影响。目前的结果对min RI作为鉴别乳腺肿瘤参数的有效性提出了质疑。Min RI并不代表实际的血流阻力。
