Detection of tumor blood flow within the spectrum, recorded peak systolic velocity (PSV) and resistance index (RI).
检测肿瘤内部的血流频谱，记录收缩期峰值流速(PSV)和阻力指数(RI)。
Objective This paper is to investigate the ratio of the systolic peak value and the end-diastolic velocity of blood flow (S/D value) and its clinical value, which can predict fetal anoxia.
目的探讨脐动脉收缩期血流峰值（S）与舒张末期血流速度（D）的比值（S/D）对预测胎儿宫内缺氧的临床价值。
