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。
Objective To evaluate the clinical value of low-field MRI in diagnosing knee joint injury. 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-fieM 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, sensibility 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.
