摘要 目的探讨椎体成形术前伤椎MRI信号特点与术后疗效的相关性。方法回顾分析河南省开封市第二人民医院68例患者,共76椎接受椎体成形术,根据MRI信号特点分为两组;A组:MRI表现为T1低信号,T2高信号或T1、T2无明显异常信号,脂肪抑制序列均为高信号;B组:MRI表现为T1、T2及脂肪抑制序列均无异常信号,与正常椎体信号一致。采用VAS评分观察术前及术后两组疼痛缓解情况,统计分析疼痛缓解情况与术前MRI信号特点的相关性。结果两组术前术后VAS评分差异均有统计学意义(P<0.05),但A组差异更大。结论 MRI信号特点为T1低信号,T2高信号或T1、T2无明显异常信号,而脂肪抑制序列均为高信号的椎体行PVP能获得较好的疗效。
