摘　　要：目的分析磁共振弥散张量成像(DTI)诊断轻度脊髓型颈椎病的应用价值。方法选取2018年2月至2019年2月在我院临床确诊为轻度脊髓型颈椎病患者67例(根据MRI平扫结果对其进行分组,其中37例患者作为A组,硬囊膜中84个节段受压,颈髓信号正常;30例患者颈髓63个节段受压,颈髓信号正常,作为B组),选取同时期在我院接受健康体检健康人100位作为对照,为C组,所有研究对象均接受常规磁共振成像(MRI)、磁共振弥散张量成像(DTI)扫描,观察分析三组表观弥散系数(ADC)值、部分各向异性(FA)之间差异。结果A、B、C组三组ADC、FA值经统计学比较均差异显著(P<0.05)。结论采用颈髓DTI技术诊断轻度脊髓型颈椎病,可在疾病早期准确量化轻度脊髓型颈椎病的颈髓微观结构变化情况,为临床医师后续疾病治疗提供有效影像学依据。Objective To analyze the value of magnetic resonance diffusion tensor imaging(DTI)in the diagnosis of mild cervical spondylotic myelopathy.Methods Sixty-seven patients with mild cervical spondylotic myelopathy who were diagnosed in our hospital from February 2018 to February 2019 were enrolled in this study.According to the MRI results,37 patients were included in group A and 84 in the hard capsule.The segments were compressed and the cervical spinal cord signal was normal.In 30 patients,the cervical spinal cord was compressed in 63 segments,and the cervical spinal cord signal was normal,as group B.100 healthy subjects in the same period were selected as healthy controls,as group C.All subjects underwent conventional magnetic resonance imaging(MRI)and magnetic resonance diffusion tensor imaging(DTI)scanning to observe and analyze the difference between the apparent diffusion coefficient(ADC)values and partial anisotropy(FA).Results The ADC and FA values of the three groups in group A,B and C were significantly different(P<0.05).Conclusion The cervical spinal cord DTI technique is used to diagnose mild cervical spondylotic myelopathy,which can accurately quantify the changes of cervical spinal cord microstructure in patients with mild cervical spondylotic myelopathy in the early stage of the disease,and provide an effective imaging basis for clinicians to follow up the disease treatment.
