MRI比较CT应用于腰椎间盘突出症诊断中的优势研究

MRI Comparative Study of the Advantages of CT in the Diagnosis of Lumbar disc Herniation

目的：探讨MRI较CT应用于腰椎间盘突出症诊断中的优势。方法：选择2016年1月-2017年1月我院收治的腰椎间盘突出症患者75例，本组患者均先采取CT检测，之后行MRI。观察对比2种检查手段对腰椎间盘突出症的诊断符合率，及对相关征象的诊断情况。结果：MRI对本组腰椎间盘突出症的诊断符合率为96．00％，高于cT的82．67％（P〈0．05）。MRI对椎间盘变化、脊髓变形、硬膜囊受压征象的诊断率高于CT（P〈0．05）；对钙化、椎间盘积气征象的诊断率低于CT（P〈0．05）；2组检查手段对神经根受压征象的诊断率对比差异无统计学意义（P〉0．05）。结论：在腰椎间盘突出症征象的诊断中，MRI与cT各具优势；但从整体来看，MRI对CT的诊疗效果更为满意，必要时可将二者联合以便提高诊疗质量。

Objective： To investigate the advantages of MRI compared with CT in the diagnosis of lumbar disc herniation. Methods： 75 cases of lumbar disc herniation were treated in our hospital from January 2016 to January -2017. All patients in this group were exam- ined by CT, and then MRI. To observe and compare the diagnostic accuracy of two kinds of examination methods for lumbar disc hernia- tion and the diagnosis of the related signs. Results： The diagnostic accuracy rate of MRI in this group of lumbar disc herniation was 96%, higher than 82.67% of CT （ P 〈 0.05 ）. MRI, changes of intervertebral disc, spinal cord deformation diagnosis of dural sac compression signs was higher than that of CT （ P 〈 0.05 ） ; diagnosis of intervertebral disc calcification, pneumatosis signs was lower than that of CT （ P 〈 0. 05 ） ; group two diagnosis of nerve root compression signs rate comparison showed no significant difference （ P 〉0. 05 ）. Conclusion： in the diagnosis of lumbar disc herniation, MRI and CT have their own advantages, but overall, MRI is more satisfactory for the diagnosis and treatment of CT. If necessary, the two can be combined, so as to improve the quality of diagnosis and treatment.
