The authors report on their experiences with ultrasonic localization of several types of IUDs. The investigations were carried out with the ultrasonic equipment-B-scanning -- Vidoson S 635 (Siemens). The characteristics of the echosonic pictures of 6 IUDs (Szontágh-IUD, Lippes-Loop, Gravigard, Alza-T, Copper-T, Antigon were studied. It could be stated that the IUDs can be well identified by ultrasonics. In cases of IUD in situ and early pregnancy the amnion and the IUD can be exactly localized.
作者报告了他们对几种类型宫内节育器（IUD）进行超声定位的经验。研究使用了超声设备——B型扫描——Vidoson S 635（西门子）。对6种宫内节育器（SZONTÁGH宫内节育器、利普斯环、格拉维加德、阿尔扎-T、铜-T、安替贡）的超声图像特征进行了研究。可以说，宫内节育器能够通过超声很好地识别。在宫内节育器在位和早期妊娠的情况下，羊膜和宫内节育器能够被精确地定位。
