Ovarian follicular growth during periovulatory period was measured using real-time ultrasound via vaginal route. In 15 patients examined preliminarily by the abdominal procedure, the mean follicular diameter increased from 15.6mm on four days before ovulation to a maximum of 21.8mm on the day of ovulation. A clear distinction of follicular development during periovulatory period could be made in 40 patients by the vaginal procedure. The mean distance between follicle and scanner was 5.6cm in the vaginal observation, which was significantly shorter than those observed in the abdominal observation. Thus, real-time ultrasound examination via vaginal route appears to be a useful technique for assessing the ovarian follicular development.
在围排卵期，通过经阴道途径采用实时超声测量卵泡生长情况。在15例最初采用经腹检查的患者中，卵泡平均直径从排卵前4天的15.6毫米增加到排卵日的最大21.8毫米。通过经阴道检查，40例患者的围排卵期卵泡发育情况可得到清晰区分。经阴道观察时卵泡与扫描仪之间的平均距离为5.6厘米，明显短于经腹观察时的距离。因此，经阴道实时超声检查似乎是评估卵泡发育的一项有用技术。
