目的：探讨高频超声在早期妊娠中的诊断价值。方法对不同孕周的1800名早孕妇女分三组给予经腹常规超声及高频超声扫查。比较高频超声与常规超声对各组妊娠囊（GS）、卵黄囊（YS）及胚胎组织的显示能力。对另300名早孕孕妇同时行经阴道及经腹部高频超声检查，比较经腹高频超声与经阴道超声（TVS）显示GS 、YS及胚胎组织的情况。结果高频超声与常规超声对GS、YS及胚胎显示率的比较，在孕龄小于4周及4～7周时，差异有统计学意义（P＜0.001）；在孕周大于等于7周时，差异无统计学意义（P＞0.1）。高频超声和TVS对GS、YS及胚胎组织三项指标的显示率比较，差异无统计学意义（P＞0.1）。结论高频超声可以明显提高小于7周的早孕GS、YS及胚胎组织的显示率，与TVS类似，且图像清晰，操作简便，值得临床应用。

Objective To evaluate the diagnostic efficacy of high-frequency ultrasound(US)in early pregnancy.Methods 1800 pregnant women of different gestational age underwent routine and high-frequency trans-abdominal US.The image quality of gestational sac(GS),yolk sac(YS)and embryo was compared.300 pregnant women also underwent trans-vaginal US examination and the image quality of GS,YS and embryo was compared with trans-abdominal high-frequency US.Results The image quality of GS, YS and embryo was significantly better on high-frequency than conventional trans-abdominal US at gestational age of less than 4 weeks and at 4-7 weeks(P<0.001).At gestational age≥7 weeks,there was no significant difference(P>0.100).There was no significant difference between tran-vaginal US and high-frequency US(P>0.100).Conclusion High-frequency US can improve visibility of GS,YS and embryo at less than 7 weeks of gestation similar to trans-vaginal US with good image quality and easy operability.
