对妊娠合并宫内发育迟缓(IUGR)有关胎盘血流量的报导一直有争论。多数学者观察到在 IUGR 中子宫胎盘血流量明显减少,而其他学者却未能证实。本文作者发现一种用放射性同位素显示宫旁组织称为最大灌注时间图像的新方法,用来测定胎盘血流量,以早期揭示胎盘功能不足。绘制的图像,可以区分胎盘的血管相和绒毛间隙相。绒毛间隙灌注指数(IPI)是指绒毛间隙相活动时间占整个胎盘最大灌注时间的百分比,此值升高说明绒毛间隙灌注时间延长,是胎盘功能不足的表现,用以标志胎盘有病理改变,为研究 IUGR 提供了有用的资料。
Reports of placental blood flow associated with intrauterine growth retardation (IUGR) in pregnancy have been debated. Most scholars observed a significant reduction in uterine placental blood flow in IUGR, while others failed to confirm it. The authors found a new method to display paracancerous tissues with radioisotopes called maximal perfusion time images to measure placental blood flow to reveal early placental insufficiency. Draw images that differentiate placental vascular and villous gaps. Villus interstitial perfusion index (IPI) refers to the chordal phase activity time accounted for the entire placenta maximum perfusion time percentage, the increase in the value of villus gap perfusion time, is the performance of placental insufficiency, to mark the pathological changes of the placenta, as Study IUGR provides useful information.
