title: Where does magnetic resonance imaging stand in the diagnosis of knee injuries?
abstract: BACKGROUND
  The aim of this study was to determine the diagnostic value of magnetic resonance imaging (MRI) in the diagnosis of knee injuries.
  
  
  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.
  
  
  CONCLUSIONS
  MRI is a valuable tool, and according to its high NPV, normal MRI can prevent unnecessary arthroscopic interventions.
