摘要
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。
Objective To evaluate the significance of MR findings in patients with lateral ankle instability but asymptomatic ankles. Methods A total of 14 ankles in 11 asymptomatic patients were evaluated using 3. 0 Tesla MR scanners. Imaging planes included axial PD and T2 weighted sequences,coronal fat-saturated PD fast spin sequence,sagittal T1 weighted sequence,and sagittal STIR sequence. Two musculoskeletal radiologists reviewed all images to reach consensus about abnormal findings. Results A total of 7 /14（ 50%） of subjects demonstrated abnormal anterior talofibular ligament（ ATFL）,8 /14（ 57%）demonstrated abnormal calcaneofibular ligament（ CFL）,and 2 /14（ 14%） demonstrated abnormal posterior talofibular ligament（ PTFL）. In addition,9 /14（ 64%） subjects were noted to have peroneal tendon pathology. Conclusion MR abnormalities in the lateral ligament complex and peroneal tendons can frequently be present in asymptomatic subjects.
