摘要
目的:探讨脊髓型颈椎病(CSM)患者脊髓MRI T2WI高信号的危险因素。方法 :2014年1月2014年4月因CSM于我院骨科行手术治疗的185例患者被纳入研究。将脊髓MRI T2WI高信号分为3级:0级,无高信号;1级,T2WI有模糊而边界不清的高信号,且高信号范围局限于一个节段;2级,T2WI有明亮而边界清晰的高信号或高信号范围超过一个节段。在MRI T2WI横断位上测量脊髓压迫程度,在过伸、过屈位X线片上测量颈椎节段和整体活动度。对可能影响高信号的因素(性别、年龄、病程、术前mJOA评分、脊髓压迫程度、颈椎活动度、椎间盘退变程度)行单因素分析,挑选出有意义指标(P<0.1)行有序Logistic回归分析。结果:脊髓MRI T2WI高信号的发生率为72.4%。按照分级标准,0级51例(27.6%),1级86例(46.5%),2级48例(25.9%)。性别和脊髓压迫程度对高信号的影响有统计学意义(女性相对于男性的OR=0.366,脊髓压迫比值的OR=0.904,P<0.05),而年龄、病程、术前mJOA评分、椎间盘退变程度、颈椎活动度与高信号均无明显相关性(P>0.05)。结论:男性、脊髓压迫程度重为CSM患者脊髓MRI T2WI高信号的独立危险因素。
