In a clinical experiental report the ultrasonic placentography is evaluated as a very reliable method in the diagnosis of pathological insertion and in the differentiation between the low lying placenta and the placenta praevia. In late pregnancy a control examination is required to find a favourable development as a result of the placental migration.
在一份临床实验报告中，超声胎盘造影术被评估为诊断胎盘异常附着以及区分低置胎盘和前置胎盘的一种非常可靠的方法。在妊娠晚期，由于胎盘迁移，需要进行对照检查以发现良好的发育情况。
