多排螺旋CT在颌面外伤骨折中的临床应用

The clinical application of multi-slice spiral CT in the maxillofacial trauma fractures

目的研究比较64层多排螺旋CT在颌面骨折中的应用价值。方法 223例骨折患者,患处薄层CT扫描及根据具体情况选择重建(MPR、SSD、MIP、4D、SVR、CPR等),观察比较影像效果。结果三维CT重建对上颌骨、下颌骨、颧骨颧弓骨折的诊断符合率分别为95.8%、97.6%、96.6%,而X线平片对上颌骨、下颌骨、颧骨颧弓骨折的诊断符合率分别为62.0%、81.6%、75.3%。三维CT影像清晰,直观立体,多角度多方位观察骨折、脱位、病变及周围关系一目了然。结论多排螺旋CT多种重建功能丰富了影像信息,为骨折的临床诊断和治疗提供精确、直观的可靠依据。

Objective To assess and compare the application value of 64-slice spiral CT in the maxillofacial fractures.Methods The thin-section CTS can of the 223 cases of fracturened and choose MPR,SSD,MIP,4D,SVR,CPR,etc.according to the specific circumstances in the reconstruction of affected area.We observed and compared image effects.Results The diagnosis rates of three-dimensional CT reconstruction of the maxilla,mandible,zygomatic fracture were 95.8%,97.6%,96.6%,while the diagnosis rate of X-ray of the maxilla,mandible,zygomatic fracture were 62.0%,81.6%,75.3%.Three-dimensional CT images were distinct and intuitive to observe fracture,dislocation,and the structure around the lesions.Conclusions Multi-slice spiral CT can enhance image information,which provides accurate,intuitive and reliable basis for clinical diagnosis and treatment of fractures.
