对比多层螺旋CT三维重建技术和X线在肩胛骨骨折术前及痊愈评估中的应用价值

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(P0.05)。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。

Comparison of the Application Value of Three-dimensional Reconstruction Technique of Multi-slice Spiral CT and X-ray in the Preoperative Evaluation of Scapular Fractures

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 51cases 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 3D image reconstruction technique of multi-slice spiral CT is of high application value in the preoperative evaluation of scapular fractures.
