目的：讨论多层螺旋CT图像后处理技术对外伤患者脊柱骨折的诊断价值。方法共纳入50例初步诊断为外伤脊柱骨折患者作为研究对象，所有患者均行MSCT检查，并行多平面重建(MPR)、最大密度投影(MIP)、三维容积漫游(VRT)等，比较其显示差异。结果50例患者随访6个月共确诊骨折线180条，其中MPR骨折线检出率最高，为97.7%，其次为轴位图像，检出率为90.0%，其余图像处理技术检出率相对比较低。MPR椎管狭窄及小关节脱位检出率最高，分别为40.0%、36.0%，其次为MIP，分别为38.0%、34.0%。结论 MSCT通过图像后处理技术可以直观、有效、立体的、清晰的进行骨折部位的检查，其中MPR检查价值相对比较高，可以为临床治疗提供积极的指导作用。%Objective To discuss the application of multislice spiral computed tomography (MSCT) recon-struction techniques in the evaluation of spinal fractures. Methods Fifty patients with clinically suspected spinal frac-ture underwent MSCT scans and additional MPR, SSD and MIP were performed subsequently. Then all the results were compared. Results After 6-month follow-up, 180 fracture lines were confirmed. The detection rate of fracture line by MPR was the highest (97.7%), followed by MSCT with a detection rate of 90.0%. The detection rates of steno-sis and small joint dislocation by MPR were highest, which were 40.0%and 36.0%respectively. By using MPR, those were 38.0%and 34.0%respectively. Conclusion MSCT reconstruction can clearly, completely, stereoscopically and directly show the details of spinal fractures, which would be reliable for providing evidence for selecting the treatment protocol and determining the operation pathway.
