A review is presented of the diagnostic applications of the ultrasonic scan technique in obsterics. In the 1st trimester of pregnancy the demonstration of the gestational sac and of an embryo is most important. During the further course of pregnancy the growth of the gestational sac and motions of the fetus can be observed. A disturbance in the development of the pregnancy can be deduced from these parameters. The various types of abortion can be differentiated by means of the scan. In the 2nd trimester the biometry of the fetus is most important. The motion behaviour of the fetus seems to be a good indicator of its well-being. The location of the placenta and the evidence of twins are easily demonstrable. In the 3rd trimester the biometry of the fetus is a good parameter of its maturity. The diagnosis of the fetal position is important for the management of delivery. Apart from these applications of ultrasound in obstetrics, the procedure is of great value in the diagnosis of tumours and the measurement of the true pelvis in pregnancy.
本文综述了超声扫描技术在产科的诊断应用。在妊娠早期，显示妊娠囊和胚胎最为重要。在妊娠的后续过程中，可以观察到妊娠囊的生长和胎儿的活动。从这些参数可以推断出妊娠发育的异常情况。通过扫描可以区分各种类型的流产。在妊娠中期，胎儿生物测量最为重要。胎儿的活动行为似乎是其健康状况的良好指标。胎盘的位置和双胞胎的迹象很容易显示出来。在妊娠晚期，胎儿生物测量是其成熟度的良好参数。胎儿位置的诊断对分娩管理很重要。除了超声在产科的这些应用外，该检查在肿瘤诊断和妊娠期真骨盆测量方面也具有重要价值。
