摘要
目的探讨腰椎间盘突出MRI与CT诊断的效果及应用价值。方法选取本院2016年8月至2017年8月收治的拟诊为腰椎间盘突出患者75例为研究对象,均接受MRI和CT诊断,以最终手术结果为准,对两种检查方式的诊断准确率、影像征象、特异度、敏感度进行比较。结果手术最终结果证实为腰椎间盘突出71例,其他4例。MRI诊断准确率为96.00%,特异度和敏感度分别为75.00%、97.18%,明显较CT的84.00%、50.00%、85.92%高(P<0.05);两种检查方式对神经根受压征象的诊断差异无统计学意义(P>0.05),CT对钙化、椎间盘积气征象的诊断优于MRI(P<0.05),MRI对椎间盘变性、硬膜囊受压征象的诊断优于CT(P<0.05)。结论 MRI与CT均是诊断腰椎间盘突出的可靠方法,两者各有优劣,但MRI检查较CT有更高的诊断准确率,临床可将两者结合,以此减少漏诊和误诊。
Objective To investigate the diagnostic value and clinical value of MRI and CT in lure bar disc herniation. Methods A total of 75 cases of lumbar intervertebral disc herniation in our hospital from August 2016 to August 2017 were selected as the subiects. The patients were diag nosed with MRI and CT, and the results of the final operation were accurated. The diagnostic ac curacy, image signs, specificity and sensitivity of the two methods were compared. Results To tally 71 cases of lumbar disc herniation were confirmed by surgery, and the other 4 cases. The di agnostic accuracy of MRI was 96. 00%, specificity and sensitivity were 75.00%, 97.18%, higher than CT （84.00%, 50.00% and 85. 92%）（P〈0. 05）. There were no significant difference in the diagnosis of nerve root compression signs（P〈0.05）. The diagnosis of CT on calcification and in tervertebral disc gas signs was superior to MRI（P〈0.05）. The diagnosis of MP, I on interverte bral disc degeneration and dural sac compression was better than CT（P〈0.05）. Conclusion Both MRI and CT are reliable methods for the diagnosis of lumbar intervertebral disc herniation. Both of them have advantages and disadvantages, but MRI examination has a higher diagnostic accuracy than CT. We can combine the two in order to reduce missed diagnosis and misdiagnosis.
