近年开展的体外授精-胚胎移植(IVF-ET)、受精卵卵管内移植(GIFT)开拓了治疗不孕症的新领域。但此法却不能准确判断卵泡发育状态与排卵时期,其成功率尚不高。超声断层为动态观察卵泡发育提供了有力手段,且操作简便能及时得出可靠结论。常用的超声装置以线型扫描式腹式电子断层为主。最近研究的扇型扫描式阴道探子法,在观察卵泡发育上比腹式线型电子断层法优点更多。一、超声观察卵泡的途径1.阴道探子(tramsvaginal probe)近年,经阴道超声观察卵泡发育在欧美发展很快,日本近年也已普及。我们于1986年开始在日常妇
In recent years, in vitro fertilization - embryo transfer (IVF-ET), fertilized egg intrabronchial transplantation (GIFT) opened up new areas of infertility treatment. However, this method can not accurately determine the state of follicular development and ovulation, the success rate is not high. Ultrasound tomography provides a powerful means for dynamically observing the development of follicles, and the simple operation can lead to reliable conclusions in time. Commonly used ultrasound devices to linear scanning abdominal electronic tomography. The recent study of the fan-type scanning vaginal probe method, in the observation of follicular development than abdominal linear electron tomography more advantages. First, the ultrasound observation follicular approach 1. Vaginal probe (tramsvaginal probe) In recent years, transvaginal ultrasound observation of follicular development in Europe and the United States has developed rapidly, Japan has also been popularized in recent years. We started in 1986 in everyday women
