摘要
目前磁共振成像(Magnetic resonance imaging,MRI)是诊断脊髓型颈椎病(CSM)的最佳手段,能清楚显示受压颈髓信号的改变,以此明确疾病进展,但病情常呈隐匿性进展,当临床症状已经相当严重时,病程已经发展至不可逆期,手术预后较差。而磁共振扩散张量成像(DTI)对CSM的诊断具有较高的敏感度。现在就DTI扫描技术、相关指标、成像原理及其对CSM的诊断意义作一综述。
Iowadays MRI is the best choice in the diagnosis of cervical spondylotic myelopathy（CSM）.It can help identify the disease progression with the signal changes of the compressedspinal cord.However,it is generally too late when signal changes was observed, and it is irreversible.Early diagnosis is the best time for treatment.Diffusion tensor imaging（DTI）is valuable for the diagnosis of CSM in the early stage.This article reviews the principle,related parameters,scanning technique and the diagnostic value of DTI in CSM.
