BACKGROUND
The aim of this study was to determine the diagnostic value of magnetic resonance imaging (MRI) in the diagnosis of knee injuries.
MATERIALS AND METHODS
Ninety-eight consecutive patients were enrolled in the study. In all patients, MRI and arthroscopy were performed and the results were compared.
RESULTS
MRI was most sensitive in the detection of medial meniscus injuries, and the highest specificity and negative predictive value (NPV) were found in the detection of posterior cruciate ligament injuries.
CONCLUSION
MRI is a valuable tool, and according to its high NPV, normal MRI can prevent unnecessary arthroscopic interventions.
背景
本研究的目的是确定磁共振成像（MRI）在诊断膝关节损伤中的诊断价值。
材料与方法
连续纳入98例患者进行研究。对所有患者均进行了MRI和关节镜检查，并比较了结果。
结果
MRI在检测内侧半月板损伤方面最敏感，在检测后交叉韧带损伤方面具有最高的特异性和阴性预测值（NPV）。
结论
MRI是一种有价值的工具，根据其高NPV，正常的MRI可避免不必要的关节镜干预。
