产前二维及三维超声诊断胎儿畸形的对比研究

A Comparative Study between Two-and-three-dimensional Ultrasonography In Prenatal Fetus Diagnosis

目的:通过比较二维及三维超声对胎儿畸形的检出率,评价其在产前断中的优劣。方法:二维及三维超声检查65例,比较、并评估两者提供的诊断信息有无差别。结果:三维超声胎儿畸形检出率(90.7%)明显优于二维超声(73.8%)尤其是在胎儿颅面部及体表畸形中,三维超声可提供更多诊断信息。结论:三维超声在产前胎儿畸形的诊断中有广泛的应用前景。

Objective：To investigate the value of fetus diagnosis by two-and threee dimensional ultrasonography in fetal malformation.Methods： Both 2DUS and 3DUS were used to examine 65 case,the diagnostic levels of 3DUS were compared and diagnostic information provided by two methds was evaluted result.Results： 3DUS provided more diagnostic information than 2DUS 3DUS had particular advantages over 2DUS in evaluating the fetal malformation of craniunrface and body surface with（93.7%~82.7% respectively）.Conclusions： 3DUS has a widespred perspective in prenatal fetus diagnostic.
