产科是超声诊断应用最广泛的领域之一,其应用价值优于其他影像学检查,避免了X线对母儿的不良影响[1]。超声检查既能直接观察到胚囊暗区、卵黄囊、胚芽及原始心管搏动或胎儿胎动,也能对节育器的形态、型号、位置与胚囊的距离进行准确的判定[2]。本文对我所2006年1月至2015年6月67例带环妊娠的超声检查进行了回顾性分析,现总结如下。 Obstetrics is one of the most widely used fields of ultrasound diagnosis, its application value is superior to other imaging studies, to avoid the adverse effects of X-ray on the mother and child [1].

This article from my January 2006 to June 2015 67 cases of pregnant women with a retrospective analysis of the ultrasound, are summarized below.
