摘要 脊髓型颈椎病(cervical spondylotic myelopathy,CSM)是脊柱外科常见的颈椎退变性疾病,是颈髓长期受压变性所引发的一系列脊髓功能受损的临床症候群。磁共振(magnetic resonance imaging,MRI)因可清楚地显示脊髓受压程度和髓内信号改变,已广泛应用于CSM的临床影像诊断。CSM脊髓MRI信号改变是指CSM患者颈椎MRI中,在颈髓受压部位和(或)相邻部位,T2WI出现一个或多个边缘模糊或清晰的高信号区(increased signal intensity,ISI),可同时伴有T1WI低信号(10wsignalintensity,LSI)。自Takahashi等于1987年首先报道CSM患者颈椎MRI出现髓内ISI至今,CSM脊髓MRI信号改变得到越来越多学者的关注和研究.但其临床意义尚存在较大争议,尤其体现在脊髓MRI信号改变与临床预后关系方面。现将近年来关于此方面的研究进展综述如下。
