摘要 目的:对利用MRI诊断膝关节周围隐匿性骨折125例进行分析,以探讨膝关节周围隐匿性骨折MRI诊断的临床价值。方法:对125例有明确外伤史,临床症状明显但平片检查阴性患者行MRI检查。使用GE signaprofile 0.2T永磁低场强MRI系统及Siemens Avanto I-Class 1.5T超导高场MRI系统。采用常规SE序列T1WI成像、快速SE序列T2WI成像和STIR脂肪抑制序列。结果:125例患者共有189处骨髓信号异常,158处为T1WI低信号、T2WI高信号,31处为T1WI低信号、T2WI混杂信号。STIR脂肪抑制序列均为明显高或混杂偏高信号。结论:MRI是早期诊断隐匿性骨折的理想方法,STIR脂肪抑制序列最为准确和敏感。
