【摘要】 目的　应用三维阴式超声表面成像技术诊断妊娠 9～ 10周的胎芽胎儿生理性脐疝 ,就其诊断价值与二维阴式超声进行比较。方法　应用Medison 80 0 0Live三维阴式容积探头对 30例妊娠 9～ 10周的胎芽胎儿腹部脐带根部进行二维扫查及三维表面重建观察。结果　应用三维阴式超声看到生理性脐疝 2 5例 ,显示率为 83% (2 5 30 ) ,二维阴式超声显示率为 2 0 % (6 30 )。结论　三维阴式超声在诊断妊娠 9～ 10周的胎芽胎儿生理性脐疝中图像逼真直观 ,尤其通过其旋转功能大大提高了诊断率 ,也使产前检查脐膨出成为了可能更多还原

【Abstract】 Objective To use transvaginal three dimensional ultrasonography (3DUS) to detect fetal physical umbilical inflation in 9～10 gestational week, and to compare its diagnostic value with the two dimensional ultrasonography (2DUS) Methods The roots of the umbilical cords in 30 fetuses of 9～10 gestational week were detected by transvaginal 3DUS and 2DUS, respectively Results In all the 30 cases, 25 physical umbilical inflations were found by 3DUS (83%), while 6 were found by 2DUS (20%) Conclusion 3DUS is more direct and precise in diagnosis of physical umbilical inflation in fetuses of 9～10 gestational week; further more, it provides the possibility of diagnosing fetal umbilical inflation before labor更多还原
