      【摘要】 目的 探讨低场强磁共振对膝关节损伤的临床诊断价值。方法 回顾性对比84例膝关节损伤患
者的低场强MRI图像和关节镜结果，统计低场强磁共振诊断的准确性、敏感性和特异性。结果 84例患者共88
个膝关节，MRI诊断半月板撕裂的准确性为82.95%、敏感性为75.51%、特异性为85.83%；诊断前交叉韧带撕裂的
准确性、敏感性和特异性分别为 89.77%、89.47%和 90.00%。结论 低场强磁共振能够清楚显示膝关节受损情
况，具有较高的临床实用价值。

【Abstract】 Objective To evaluate the clinical value of low-field MRI in diagnosing knee joint inju-
ry. Methods The MRI and arthroscopy results of 84 cases of knee joint injuries were retrospectively analyzed and
compared. Then the accuracy, sensibility and specificity of low-field MRI were evaluated. Results There were 84
cases with 88 knee joint injuries. The accuracy of low-field MRI was 82.95% in diagnosing meniscus tear, with the
sensibility of 75.51% and the specificity of 85.83%. In diagnosing anterior cruciate ligament tear, the accuracy, sensi-
bility and specificity of low-field MRI were 89.77%, 89.74% and 90.00%, respectively. Conclusion Low-field MRI
can demonstrate knee joint injuries very clearly, and it has high clinical practical value.
