A new method for measuring regional distribution of placental blood flow is presented. After 2-5 mCi of 133Xe saline has been injected intravenously, the counts over the placenta are registered with a scintillation camera interfaced with a digital data storage and television readout system. Using "area of interest" technique, time activity curves are obtained for different regions. Analysis of the curves is based on two-exponential curve fitting. In normal pregnancy the mean intervillous flow in 16 healthy women was 125 ml/min/100 ml and myometrial flow 17 ml/min/100 g. The intervillous flow in the central part of the placenta was 55% higher than in the marginal parts. The myometrial flow in the placental area was nearly the same as outside the placenta.
本文介绍了一种测量胎盘血流区域分布的新方法。静脉注射2 - 5毫居里的133Xe盐水后，用与数字数据存储和电视读出系统相连的闪烁照相机记录胎盘的计数。采用“感兴趣区”技术，获得不同区域的时间-活性曲线。曲线分析基于双指数曲线拟合。正常妊娠时，16名健康女性的平均绒毛间隙血流为125毫升/分钟/100毫升，子宫肌层血流为17毫升/分钟/100克。胎盘中央部分的绒毛间隙血流比边缘部分高55%。胎盘区域的子宫肌层血流与胎盘外几乎相同。
