摘要
目的探讨腰椎间盘退行性病变诊断中CT与MRI的应用价值。方法 按照随机抽样的方式选取我院2013年2月~2016年4月接诊的确诊为腰椎间盘退行性病变患者50例进行研究,纳入研究对象临床资料完整,签署知情同意书愿意配合本次研究,均实施CT与MRI诊断,比较两种方法诊断结果。结果 MRI诊断椎间盘突出、椎间盘狭窄、椎间盘突出时硬膜囊分界清晰率高于CT诊断,其中中度与重度椎间盘突出时硬膜囊分界清晰率显著高于CT诊断(P〈0.05),而CT诊断在椎间盘积气率、纤维环和髓核钙化率方面显著高于MRI诊断(P〈0.05)。结论 腰椎间盘退行性病变采取CT诊断与MRI诊断均有较好效果,但二者均有优劣,临床诊断建议结合二者联合诊断,以提高诊断符合率,为诊治提供更高的价值。
Objective To discuss the application value of CT and MRI in diagnosis of lumbar intervertebral disc degeneration diseases(DDD). Methods 50 DDD patients with complete clinical data and signed informed consent who were treated in our hospital from February 2013 to April 2016 were selected by random sampling. The patients were given diagnosis by CT and MRI, and the diagnostic results of the two methods were compared. Results The performance of MRI was better than CT in diagnosis of protrusion of intervertebral disc, stenosis of intervertebral disc, and definition of dural sac in protrusion of intervertebral disc. In moderate and severe protrusion of intervertebral disc, the definition of dural sac by MRI was significantly higher than that of CT(P0.05). The performance of CT was significantly better than MRI in detection of pneumatosis rate of intervertebral disc, fibrous rings, and calcification of nucleus pulposus(P0.05).Conclusion Both CT and MRI have favorable effects in diagnosis of DDD, and each has advantages and disadvantages.In clinical practice, it is recommended to combine these two methods to improve the diagnostic accordance rate and provided higher diagnostic value.
