多层螺旋CT后处理技术在脊柱外伤中的应用

目的探讨多层螺旋CT(MSCT)后处理技术在脊柱外伤诊断中的应用价值。方法回顾分析44例脊柱外伤病例,均行16层螺旋CT检查后,传输到工作站进行MPR、SVR成像,并与2D图像进行比较。结果MPR、SVR图像清晰、直观显示骨折线的部位、形态,断端移位情况及空间关系,MPR图像能观察细小骨折,准确判断关节脱位。结论MPR及SVR重建图像是2D图像的重要补充,三者的有效结合,为脊柱外伤提供了丰富的空间结构信息,对治疗方案的选择及预后的估计有重要价值。

The Evaluation of Spinal Injury with Multi-slice Spiral CT Post-processing Technique

Objective To evaluate the value of multi-slice spiral CT(MSCT) post-processing technique in diagnosis of spinal injury. Methods CT materials in 44 cases of spinal injury were retrospectively analyzed,all case were scanning with 16-slice helical CT,the images were passing on an independent workstation for MPR and SVR technique,and compared with axial 2D imaging of CT . Results MPR and SVR images could show the fracture line and displacement of fractured osseous fragments and spatial relationship of structure clearly,MPR images could show small fracture line and dislocation of joint actually. Conclusion MPR and SVR images are important supplement to axial 2D images,the axial imaging combined with various reconstruction technique can provide the space structure of spinal injury ,and play an important role in selecting therapy project and evaluating prognosis.
