Dimensiona ultrasonography data of 29 cases fetal anomaly between 24 and 40 weeks' gestation from Jan 2003 to Dec 2006. Results Among them, there were 11 cases of cheilognathus,7 cases of anencephalus, 4 cases of anomaly of extremities, 3 cases of omphalocele, 3 cases of lymphocyst at the neck and 1 case of amniotic band syndrome. The anomaly features are consistent with those of the born fetuses. Conclusion The three??

大部分解剖结构明显异常的畸形一般通过二维实时超声在22周左右即可做出诊断［1］，但胎儿体表结构有较复杂的曲面改变，二维超声可能漏诊、误诊胎儿体表畸形。20世纪80年代末应用于临床的三维超声成像，是检测胎儿发育状况的有效方法，大大提高了产前诊断的准确率，尤其在检测胎儿畸形方面具有独特优势［2］。
