This study proposes to correlate the placental grade as described from real-time ultrasound examination with the impedance to blood flow in the fetal thoracic aorta, umbilical artery, and the accurate branches of the uterine artery, and the mean umbilical vein flow in a group of patients at risk for intrauterine growth retardation, based on clinical and historical factors between 26 and 42 weeks' gestation.

本研究建议将所述胎盘级别与 从实时超声检查到血液阻抗 胎儿胸主动脉、脐动脉和 子宫动脉的准确分支，以及平均脐动脉 一组有宫内生长风险的患者的静脉血流 根据26岁之间的临床和历史因素， 怀孕42周
