| 摘 要： | 目的 回顾性分析寰枢椎骨折的多排螺旋CT扫描及后处理重建的诊断价值。方法 收集寰枢椎骨折患者4 4例 ,其中寰椎骨折脱位 2 0例 ,枢椎骨折 2 4例 ,所有患者经多排螺旋CT扫描后 ,经MPR与 4D -Angio后处理重建 ,分析不同处理后图象的应用价值。结果 多排螺旋CT及后处理技术可显示骨折部位与类型 ,其MRP与 4D -Angio重建不仅显示寰齿间隙的变化 ,寰齿前间隙的增宽提示横韧带的损伤 ,更可显示齿状突骨折移位的状况。结论 MSCT可清晰评价寰枢椎骨折部位、程度、脱位与否以及骨折类型。

| Abstract: | Objective The retrospective evaluation intends to demonstrate the advantages of using the Multiple-slice CT (MSCT)for the Atlas-Axis fracture. Methods 22 patients involving the Atlas-Axis fracture and dislocation were scanned by the MSCT. The raw data were post-processed with the Mulitple Plannar Reconstruction(MPR) and the 4 Dimensional-angiotechnique (4D-Angio). Results The MSCT can show not only the location and type of fracture, but also the changes of AO (Atlas-Odontoid) distance and the lesion of transverse ligament of the atlas. Conclusion The MSCT can be used to show the location, dislocation and types of Atlas-Axis fracture, and to evaluate the levels of lesion. |
