3.0T磁共振成像评价踝关节运动损伤的应用价值

Application Value of 3.0 Tesla Magnetic Resonance Imaging in Evaluation of Ankle Sport's Injury

目的探讨3.0T磁共振成像对踝关节运动损伤的应用价值.方法回顾性分析临床确诊的28例踝关节损伤患者,以踝关节镜检/切开手术为标准,统计分析MRI检查对踝关节运动损伤的敏感性及诊断价值.结果 6例踝关节骨折MRI均正确诊断,对骨髓挫伤水肿的诊断敏感性达100%;19例临床确诊踝关节韧带损伤中,MRI诊断16例,总体敏感性达84%.8例跟腓韧带损伤MRI正确诊断6例,敏感性为75%.结论 3.0 TMRI检查对韧带、肌腱、软骨损伤具有较高的敏感性,可以很好显示踝关节损伤,为临床早期治疗及康复提供客观依据.

Objective To investigatie the application value of 3.0 Tesla magnetic resonance imaging in ankle sport’s injury.Methods Twenty-eight cases of ankle sports injury confirmed by clinical operation or ankle arthroscope and underwent magnetic resonance imaging were analyzed retrospectively.Regarding clinical operation or ankle arthroscope as the standard,the sensitivity and diagnostic value of magnetic resonance imaging in ankle sport’s injury was statistically analyzed.Results Six cases of ankle fracture were correctlly diagnosed by MRI,and bone marrow edema was confirmed by MRI meanwhile,MRI showed 100% sensitivity in diagnosis of ankle fracture and bone marrow edema.In nineteen cases of ankle ligaments injury confirmed by clinic,MRI detected sixteen cases,the sensitivity of diagnosis was 84%.MRI detected six cases in eight cases of calcaneofibular ligament injury,the diagnostic sensitivity was 75%.Conclusions 3.0 Tesla MRI has high sensitivity in diagnosis of ankle fracture,bone marrow edema,Ligament and tendons and cartilage damage,can discover ankle’s injury in earlier stage,and provide objective basis for earlier therapy and rehabilitation of an ankle fracture.
