颈脊髓MRI信号增强与脊髓型颈椎病手术指征

Effect of signal intensity enhancement of the spinal cord MRI and the indications of surgical treatment in cervical spondylotic myelopathy

目的 :探讨脊髓MRI信号增强能否作为脊髓型颈椎病 (CSM)脊髓减压的指征。方法 :总结 87例轻型CSM病人保守治疗随访结果与颈脊髓T2加权信号增强 (ISI)的关系。结果 :有ISI组与无ISI组、ISI减少组与ISI无变化组治疗前、后JOA评分无明显差异 ;ISI减少、无变化或无ISI均不影响保守治疗满意率。结论 :对轻型CSM 。

Objective:To investigate whether increased signal intensity(ISI) of spinal cord could be regarded as one of the operative signs for mild cervical spondylotic myelopathy(CSM).Method:Eighty seven patients with mild CSM underwent conservative treatment and followed up for 28 months.The outcome was assessed using the Japanese Orthopedic Association Score(JOA score) and compared with T2 weighted axial images of cervical spinal cord which showed ISI.Result:No statistically significant difference was seen between group with ISI and without ISI,between group of ISI reduction and no change of ISI in JOA scores before and after treatment.The satisfactory ratio of conservative treatment was not affected by whether there was ISI and ISI reduction or not.Conclusion:ISI should not be regarded as a routine sign for mild CSM patients.
