目的 比较MRI与CT在椎间盘突 出的诊断价值差异及其临床应用价值。 方法 选择我院2012年6月-2015年6月 收治53例腰椎间盘突出症展开研究， 均行CT检查与MRI检查，比较两种检查 方法的诊断准确率。结果 MRI对椎间 盘突出、椎间盘游离的诊断准确率均 达到100.0%，明显高于CT诊断结果， 差异有统计学意义(P＜0.05）；MRI总 检出率为94.8%(55/58)，明显高于对照 组70.7%(41/58)，差异有统计学意义(P ＜0.05）。结论 与CT检查相比，MRI在 椎间盘突出症临床诊断中的应用具有更 高诊断准确率，临床应用价值更大，但 CT检查同样有其自身优点，临床可结合 实际选择合适检查方法，并将两种方法 积极结合，以提高诊断准确率，利于临 床治疗。

Objective To compare the difference between MRI and CT in the diagnosis of lumbar disc herniation and the clinical application value. Methods 53 cases of lumbar disc herniation who were admitted into the hospital during June 2012 to June 2015 were studied. All patients underwent CT and MRI examination. The diagnostic accuracy of the two methods was compared. Results The diagnostic accuracy of MRI in the diagnosis of lumbar disc herniation and intervertebral disc dissociation was 100% which was significantly higher than that of CT. The difference was statistically significant (P<0.05). The total detection rate of MRI was 94.8% (55/58) which was significantly higher than 70.7% (41/58) in the control group and the difference was statistically significant (P<0.05). Conclusion Compared with CT, MRI is of higher diagnostic accuracy in the clinical diagnosis of lumbar disc herniation and the clinical application value is greater, but CT has its own advantages. In clinic, suitable examination method can be chosen according to the practice and the two methods can be combined to improve the diagnostic accuracy, which is helpful to clinical treatment.
