摘要 目的探讨磁共振二维扰相梯度回波小角度激励序列(FLASH-2D)在半月板损伤中的诊断价值。方法回顾性分析55例膝关节半月板损伤的磁共振与关节镜资料。磁共振均行SE序列T1WI、PD+T2WI矢状位和冠状位扫描及FLASH-2D序列矢状位扫描。以关节镜为标准,对比半月板损伤在磁共振各种成像序列中的显示情况。结果本组关节镜检查诊断半月板损伤51例,SE序列T1WI、PD+T2WI正中矢状位和冠状位诊断半月板损伤45例,敏感性为78%,特异性为90%;FLASH-2D序列矢状位诊断半月板损伤49例,敏感性为90%,特异性为97%。结论FLASH-2D序列矢状位与SE序列T1WI、PD+T2WI正中矢状位和冠状位相比,具有更高的敏感性和特异性,在半月板损伤中具有更高的诊断价值。
