动力位MRI对颈椎椎间盘突出症的诊断价值(1)
摘要:目的:探讨颈椎动力位MRI检查在椎间盘突出症的诊断价值。方法:临床疑有颈椎椎间盘突出症并行颈椎常规中立位和动力位MRI检查的60例患者。利用计算机软件对各个节段颈椎间盘突出程度进行对比分析并行统计学处理。结果:在动力位上,各节段颈椎椎间盘突出同中立位相比均有显著增加。在中立位正常或椎间盘突出<3 mm,2.57%患者在过屈位椎间盘突出进展到>3 mm,15.44%患者在过伸位椎间盘突出进展到>3 mm。在中立位椎间盘突出>3 mm 且<5 mm,3.57%患者在过屈位椎间盘突出进展到>5 mm,7.14%患者在过伸位椎间盘突出进展到>5 mm。结论:与中立位相比,动力位 MRI 上颈椎椎间盘突出更加准确。动力位 MRI 对颈椎间盘突出症的评估有其重要价值,是常规中立位的重要补充。关键词: MRI;动力位;颈椎病
