Abstract:

目的分析MRI对自感无症状的外踝不稳患者的诊断价值。方法采用3.0T核磁共振仪扫描评估11例无症状但有踝关节损伤史的患者的14侧踝关节。成像平面包括轴向PD和T2加权序列、冠状快速自旋回波脂肪饱序列、矢状T1加权序列和矢状面STIR序列。2位肌肉骨骼领域的放射学专家审阅所有图像,对于异常显现达成一致的认识。结果14侧踝关节中7例(50%)呈现距腓前韧带异常,8例踝关节(占57%)呈现跟腓韧带异常,2例踝关节(占14%)呈现距腓后韧带的异常。除此之外,9例踝关节(占64%)发现有腓骨肌腱的病理表现。结论在外踝不稳患者中,MRI可以显示外侧韧带结构以及腓骨肌腱的异常,但这些异常可以无症状。
