多层螺旋CT多平面重建及三维重建在骶尾骨骨折中的应用

目的:分析研究多层螺旋CT(Multi-slice Spiral CT,MSCT)多平面重建和三维重建技术在骶尾骨骨折中的应用价值。方法:17例骶尾骨骨折病人行MSCT扫描,图像经处理后进行多平面重建和三维重建,最后进行图像分析研究。结果:本组全部病例可以通过多平面重建和三维重建明确判断骨折情况。与CT轴位图像相比,多平面重建可多方位地显示骶尾骨骨折的情况,三维重建能立体形象地显示骶尾骨骨折的范围和方向。结论:MSCT多平面重建及三维重建技术能多方位、立体、全面地显示骶尾骨骨折部位、程度,对骶尾骨骨折的诊断及制定治疗方案具有重要的作用和临床意义。

Multi-slice Spiral CT MPR and 3D reconstruction in the diagnosis of Sacrum and Coccyx Fracture

Objective:To evaluate MSCT(Multi-slice Spiral CT) MPR and 3D reconstruction in the diagnosis of sacrum and coccyx fracture.Method: 17 patients with sacrum and coccyx fracture were examined with MSCT by using post-process of MPR and VR reconstruction.Result: All can be clearly diagnosed by MPR and 3D reconstruction.MPR demonstrated the extent better than axial CT,whereas VR images showed more exactly extent and direction than the others did.Conclusion: MSCT MPR and 3D reconstruction can display distinctly the location and degree of fracture from arbitrary direction,which is of great importance and clinical significance to the diagnosis and establishment of surgical treatment.
