摘要 目的构建基于CT数据的正常胎儿骨骼数字化重建三维模型,对该方法在胎儿骨骼发育异常产前诊断中的应用价值进行初步探讨,为异常胎儿骨骼研究设立对照。方法对2例自愿参加研究的计划生育引产孕妇(1例妊娠26+2周,1例妊娠27+4周)产前行腹部CT扫描,利用CT自带软件(MIP法及VRT法)对胎儿骨骼进行重建,同时将Dicom原始二维断层图像数据集导入Mimics 10.01软件进行胎儿骨骼三维重建,观察胎儿骨骼情况,并对各种重建方法的重建效果进行初步比较。结果利用CT自带软件及Mimics 10.01软件重建获取的胎儿骨骼数字化模型均可清楚地显示胎儿骨骼情况,以VRT重建法及Mimics10.01软件重建模型的效果更佳,重建模型不仅可以任意比例缩放和任意角度旋转以显示骨骼间的毗邻关系和空间构象,且可对其进行任意径线和角度的精确测量。结论基于CT数据,利用VRT重建法及Mimics10.01软件均可方便快捷地建立出逼真清晰的胎儿骨骼数字化三维模型。对于超声检查不能明确诊断的骨骼发育异常胎儿,必要时可以辅以CT检查并对胎儿骨骼进行三维重建以进一步明确诊断。
