摘　　要：传统MRI显示的脊髓信号变化与脊髓型颈椎病(cervical spondylotic myelopathy,CSM)的临床表现有明显的相关性,磁化转移比(magnetization transfer ratio,MTR)可以反映髓鞘的完整性和患者的严重程度,神经元定向弥散和密度成像(neurite orientation dispersion and density imaging,NODDI)能够更好地了解脊髓微观结构信息和预测患者的术后恢复,而动态MRI(dynamic MRI,dMRI)可以更准确地确定颈椎病患者的病理狭窄或压迫。对近年来磁共振成像技术在脊髓型颈椎病患者诊治方面的应用进行了综述。There is a significant correlation between the changes in spinal cord signals displayed by traditional MRI and the clinical manifestations of cervical spondylotic myelopathy(CSM),magnetization transfer ratio(MTR)reflects the integrity of myelin and the severity of the patient,neuronal orientation dispersion and density imaging(NODDI)provides better information on spinal cord microstructure and predicts the patient's postoperative recovery,and dynamic MRI(dMRI)can more accurately identify pathological stenosis or compression in patients with cervical spondylosis.The application of magnetic resonance imaging in the management of patients with spinal cord cervical spondylosis in recent years is reviewed.
