方法应用彩色超声多普勒仪器进行胎儿脐动脉血流检测，并分析胎儿及分娩前后情况与血流检测的关系。
Method The ratio of systolic and diastolic blood stream(S/D value)of umbilic artery was detected by color Doppler ultrasound detector.
目的应用彩色多普勒超声（CDFI）对胎儿宫内生长迟缓（IUGR）的脐动脉（UA）及胎儿肾动脉（RA）的血液动力学进行检测。
Objective To measure the changes of the blood hemodynamics of umbilical artery(UA)and renal artery(RA )of intrauterine growth retardation(IUGR)with color Doppler flow imaging(CDFI).
方法应用彩色多普勒超声检测70例孕妇（孕13～40周）的正常胎儿的脐动脉血流量。
Methods 70 cases pregnant women (pregnant age ranging from 13 to 40 weeks) were examined by color Doppler ultrasound to measure the umbilical artery blood flow quantities of the normal foetuses.
