多层螺旋CT容积重建技术在儿童鸡胸中的应用价值

目的：探讨多层螺旋 CT 容积重建(VR)技术在儿童鸡胸中的应用价值。方法收集在本院行多层螺旋 CT 检查的鸡胸患儿资料36例，全部病例图像均在 CT 工作站进行3D 后处理，主要方法为 VR 及多平面重建(MPR)。结果胸骨体前凸型35例，胸骨柄前凸型1例，对称型鸡胸27例，非对称型鸡胸9例。VR 技术能清楚显示胸骨、肋骨及肋软骨的异常改变。结论多层螺旋 CT VR 技术能立体、全面显示患儿鸡胸的形态改变，为微创手术矫治鸡胸畸形提供准确信息。

Value of volume rendering technique of MSCT in the diagnosis of pediatric pectus carinatum

Objective To evaluate the value of volume rendering technique of MSCT in the diagnosis of pediatric pectus carinatum. Methods MSCT data of 36 children with pectus carinatum were collected.Volume rendering and multiplanar reformation recon-struction techniques were adopted at a postprocessing station.Results There were 35 cases of chondrogladiolar variant and 1 case of chondromanubrial variant,27 cases were symmetric and other 9 cases were asymmetric.VR technique clearly demonstrated the abnormal changes of sternum,costae and costal cartilages.Conclusion VR technique of MSCT can fully display the three-dimension morpho-logical changes of pediatric pectus carinatum,which can supply accurate information for minimally invasive treatment procedure.
