多排螺旋CT对鼻骨骨折的诊断价值

The diagnostic value of multi-slice spiral CT on fracture of nasal bones

目的评价多排螺旋CT对鼻骨骨折的诊断价值。方法回顾性分析32例鼻骨骨折患者的普通X线影像及多排螺旋CT的多层面重建(MPR)及表面遮盖法三维重建(SSD)表现。结果 32例骨折患者中,X线平片显示23例,C T影像全部显示。MPR对鼻骨骨折及骨折类型显示良好,SSD在显示骨折类型方面不及MPR,但立体感强,能很好地显示骨折的空间位置。结论多排螺旋CT能准确地显示鼻骨骨折的部位、类型、程度和范围,对指导处理鼻创伤具有重要的作用。

Objective To investigate the diagnostic value of multi-slice spiral CT for fracture of nasal bones.Methods X-ray examination and multi-slice spiral CT on MPR and SSD images examination 32 doubtful cases nasal bone fracture were retrospectively analyed.Results In 32 patients,23 patients were diagnosed as fracture of nasal bones by X-ray and all patients showed fracture of nasal bones by CT.The typical bone fracture well showed by MPR,MPR was super to SSD in displaying the typical bone fracture,but in displaying three dimension,the spatial location were clear.Conclusion The fracture of nasal bone in the site,type,extent and scope can accurately showed by multi-slice spiral CT and plays an important role in treatment the nasal trauma.
