目的 本实验分别采用MRI和关节 镜对前交叉韧带损伤患者进行诊断，通过 对比这种方法检查的结果，找到MRI在诊 断前交叉韧带损伤中的存在的问题以及应 用价值。方法 本实验采用MRI技术以及关 节镜技术对54例患者进行诊断，比较两种 方法对患者的检查结果。结果 54例患者 中，通过MRI诊断出完全撕裂为21例，部 分撕裂30例，3例检查没有撕裂；而通过 关节镜检查结果为，完全撕裂22例，部分 撕裂32例。结论 通过两个方法的比较， MRI在诊断前交叉韧带损伤存在一定的假 阳性，同时由于该方法具有无创性，减少 检查对病人的风险，并且诊断准确率较 高，因此具有较好的应用价值。

Objective In this study were used MRI and arthroscopy in patients with anterior cruciate ligament injury diagnosis, and clinical diagnosis of MRI contrast difference in the results. Methods In this study, using MRI technology and arthroscopic technique in 54 patients were diagnosed analyze differences between the two methods exist. Results 54 patients, diagnosed by MRI of 21 cases of complete tear, partial tear in 30 cases, three cases check that no tear, through arthroscopy result, complete tear in 22 cases, 32 cases of partial tear. Conclusion By comparing the two methods, having MRI in the diagnosis of non-invasive, reduce detection risk to the patient, and because of the presence of MRI diagnostic errors, with false positives, requiring both methods with the completion.
