【摘要】 目的：评价三维超声成像技术在诊断胎儿畸形中的应用价值。方法：所有患者先常规作二维超声检查，之后 再由同一操作者行三维超声检查，并将二维及三维超声检查结果相对照。结果：６６例孕妇６７例胎儿中，共检查出胎儿异 常１７例，其中３例为胎儿宫内发育迟缓，１４例为胎儿畸形，余５０例未发现异常。在１４例胎儿畸形中，有８例（５７％）三维 超声可提供更多的诊断信息；有６例（４３％）二维超声即能作出诊断，三维超声未能提供更丰富的诊断信息；１４例胎儿畸形 中未发现二维超声能作出诊断而三维超声不能诊断的病例。结论：三维超声成像可对胎儿畸形的诊断提供更丰富的诊断 信息，可作为二维超声成像的有益补充。更多还原

【Abstract】 Objective:To evaluate the clinical significance of three-dimensional ultrasonography (3DUS) in diagnosing the fetal malformation. Methods: All the subjects were conventionally conducted to two-dimensional ultrasonography (2DUS) ,then to 3DUS by the same scanner.The results of 3DUS and 2DUS were compared.Results:In 14 cases of fetal malformations,3DUS could preside more diag- nostic information than 2DUS in 8 cases (57%),and provided the same information as 2DUS in the other 6 cases (43%).Cmonclusion: 3DUS may provide more diagnostic information than 2DUS,and serve as a beneficial supplement to 2DUS.更多还原
