摘要
目的探讨MRI在距骨骨软骨损伤中的诊断价值。方法回顾性分析2015年3月~2016年3月30例经临床及MRI证实的距骨骨软骨损伤的病例,经与关节镜检查对比,评价其符合率。结果踝关节MRI成像检查对距骨骨软骨损伤病灶及范围大小能清晰显示。T1加权像为距骨软骨下边界清晰的低信号区,T2像则为高信号;部分表面的关节软骨完整,部分软骨下骨囊变,并见分离的骨软骨块;关节镜检查结果,总诊断符合率为76.7%。结论 MRI诊断骨软骨损伤准确度较高,对早期诊断、早期治疗有重要指导意义,优于关节镜检查。
Objective To explore the value of MRI in diagnosing osteochondral lesions of talus.Methods A retrospective analysis of the data of 30 cases of osteochondral lesions of the talus treated from March,2015 to March,2016 and confirmed by clinical and MRI examinations was conducted.Arthroscopy was used to compared the diagnostic results to evaluate the coincidence rate.Results The MRI examination could clearly show the osteochondral lesions and their size.The T1 weighted image was the clear low signal area of subchondral boundary of talus.The T2 image was the high signal area.Some superficial articular cartilages were complete,some subchondral bone showed cystic changes,and some separated osteochondral blocks were found.According to the results of the arthroscopy,the total coincidence rate was 76.7%.Conclusion MRI is accurate and reliable for the diagnosis of osteochondral lesions.
