Transvaginal ultrasonography was done on 26 pregnant women ranging from 5 to 27 weeks of gestation and 12 patients with gynecologic diseases. In early gestation, significant correlations were found among gestational age, crown-rump length, diameter of yolk sac and fetal heart rate. The maximal length of the gestational sac did not correlate with any other parameter. Transvaginal image quality was better in 76.2% in obstetric field and in 66.7% in gynecologic field, as compared to findings with conventional abdominal ultrasonography, respectively. Fine structures and individual organs were better evidenced transvaginally. Therefore, transvaginal ultrasound affords pertinent information complementary to that obtained with the transabdominal technique.
对26例妊娠5至27周的孕妇以及12例患有妇科疾病的患者进行了经阴道超声检查。在妊娠早期，发现胎龄、头臀长度、卵黄囊直径和胎儿心率之间存在显著相关性。妊娠囊的最大长度与其他任何参数均无相关性。与传统腹部超声检查结果相比，经阴道超声图像质量在产科领域分别为76.2%，在妇科领域为66.7%。经阴道检查能更好地显示细微结构和各个器官。因此，经阴道超声提供了与经腹部技术所获信息互补的相关信息。
