[摘要] 目的 对比分析脊柱外伤的CT和MRI影像诊断价值。方法 在2018年6月—2019年6月该时间段内，从该院收治的脊柱外伤患者中方便选取84例作为样本，并进行相关的对比工作。选取的样本全部接受CT检查及MRI检查，将手术结果作为参考依据，对CT和MRI诊断价值进行比较分析。结果 CT诊断椎弓骨折及椎弓骨折线的检出率（ 57.34% 、95.74% ） 明显高于MRI（37.49%、80.95%），MRI诊断脊髓、软组织及神经根损伤的检出率（46.42%、30.95%、15.47% ）明显高于CT（38.09%、29.76%、10.71% ），差异有统计学意义（P﹤0.05）。在脊髓损伤、软组织损伤、前纵韧带、后纵韧带、神经根损伤（χ2=3.295、3.955、7.907、9.094、4.658，P=0.043、0.041、0.004、0.003、0.38）。结论 在椎弓骨折、骨折线上方面，CT表现更好，但是MRI可以更好地精准确定脊柱外伤空间，而且可以促使由于外伤造成的脊髓病变及损伤进行明显地显现。CT与MRI存在各自的优缺点，应该结合使用，实现优势互补。

[Abstract] Objective To compare the diagnostic value of CT and MRI images of spinal trauma. Methods During the period from June 2018 to June 2019， 84 cases of spinal trauma patients treated in the hospital were convenient selected as samples and related comparisons were performed. All the selected samples were subjected to CT and MRI examinations， and the surgical results were used as a reference basis to compare and analyze the diagnostic value of CT and MRI. Results The detection rates of vertebral arch fractures and vertebral arch fracture lines by CT （57.34%， 95.74%） were significantly higher than those of MRI （37.49%， 80.95%）. The detection rates of MRI in the diagnosis of spinal cord， soft tissue and nerve root injuries （46.42%， 30.95%， 15.47%） were significantly higher than CT （38.09%， 29.76%， 10.71%）， and the differences were statistically significant（P<0.05）. For spinal cord injury， soft tissue injury， anterior longitudinal ligament， posterior longitudinal ligament， and nerve root injury（χ2=3.295，3.955，7.907，9.094，4.658，P=0.043，0.041，0.004，0.003，0.38）. Conclusion CT has better performance in vertebral arch fractures and fracture lines， but MRI can better determine the spinal trauma space， and can promote the obvious manifestation of spinal cord lesions and injuries caused by trauma. CT and MRI have their own advantages and disadvantages and should be used in combination to achieve complementary advantages.

在外科中，脊柱外傷是非常常见的一种疾病，多是因为剧烈冲击等原因造成，脊柱外伤的治疗如果不能够妥当进行，会导致患者致残，严重的话还会对患者生命造成威胁。所以，科学有效地对脊柱外伤进行诊断对改善或预后有着非常大的价值。现今，在脊柱外伤上，临床上使用的影像学诊断方式非常多，在这些方法里，X线图像因为重叠图像，很难清楚地显现椎管、脊髓等的细微结构，因此临床上有一定缺陷。CT及MRI在这方面则是表现的更好，借助其分辨率好、图像清楚等优势，在临床上被广泛使用。为对比CT和MRI对脊柱外伤的诊断价值，文章以该院在2018年6月—2019年6月该时间段内收治的84例病患作为样本，并展开相关的分析研究，现报道如下。……
