【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。
[Abstract]:Objective to analyze the diagnostic value of MRI in self-sensorless lateral malleolus instability. Methods Thirty T MRI scan was used to evaluate 14 ankle joints in 11 patients with asymptomatic ankle injury. The imaging plane consisted of axial PD and T2 weighted sequences, coronal fast spin echo fat saturated sequences, sagittal T1 weighted sequences and sagittal STIR sequences at position .2 of musculoskeletal radiologists reviewing all images. An agreed understanding of abnormal appearances. Results 7 of the 14 ankle joints presented abnormal anterior talofibular ligament and 8 ankle joints (57%) showed abnormal calcaneal ligament and 2 ankle joints (14%) showed abnormal posterior talofibular ligament. In addition, the fibula tendon was found in 9 cases of ankle joint (64%). Conclusion MRI can show the abnormal structure of lateral ligament and fibula tendon in patients with lateral malleolus instability, but these abnormalities can be asymptomatic.
