摘　　要：目的探讨多层螺旋CT三维重建技术和X线在肩胛骨骨折术前及术后痊愈评估中的应用价值。方法选取医院收治的65例肩胛骨骨折作为研究对象,均行多层螺旋CT扫描,将图像输入至工作站行三维重建,并与X线检查结果对比。结果65例骨折患者中,多层螺旋CT三维图像重建技术诊断正确例数为65例,骨折分型与术中所见一致,准确率为100%;X线诊断正确例数为5 1例,准确率为78.46%。多层螺旋CT三维图像重建技术诊断准确率显著高于X线,差异具有统计学意义(P<0.05)。多层螺旋CT三维图像重建技术图像可清晰显示骨折凹陷、移位、累及范围及骨折块数目,对于移位不明显的非粉碎性骨折表现为骨折线;复查时可清楚观察到钢板、固定情况及骨折复情况;而X线无法清晰显示骨折移位及病变程度。结论多层螺旋CT三维重建技术在肩胛骨骨折术前评估具有较高的应用价值。Objective To investigate the application value of three-dimensional reconstruction technique of multi-slice spiral CT and X-ray in the preoperative evaluation of scapular fractures. Methods 65 cases of patients with scapular fractures in the hospital were selected as the research objects. All of the patients underwent multi-slice spiral CT scanning, and the images were inputted to the workstation for 3D reconstruction and were compared with the results of x-ray examination. Results Among the 65 cases of fracture patients, there were 65 cases who were correctly diagnosed by 3D image reconstruction technique of multi-slice spiral CT. The fracture classification was consistent with that seen during operation and the accuracy rate was 100%. The correctly diagnosed cases of X-ray were 51 cases and the accuracy rate was 78.46%. The diagnostic accuracy rate of 3D image reconstruction technique of multi-slice spiral CT was significantly higher than that of X-ray, and the difference was statistically significant（P〈0.05）. 3D image reconstruction technique of multi-slice spiral CT can clearly show the depression, displacement, the involved range and number of fractures. For non-comminuted fracture of unconspicuous displacement, it manifested as fracture line. When reexamined, the plates, condition of fixation and fracture recovery could be clearly observed. However, X-ray could not clearly show the fracture displacement and the degree of lesions. Conclusion Conclusion 3D image reconstruction technique of multi-slice spiral CT is of high application value in the preoperative evaluation of scapular fractures.
