title: Arthroscopic and low-field MRI (0.25 T) evaluation of meniscus and ligaments of painful knee.
abstract: OBJECTIVE
  Magnetic resonance imaging (MRI) is an accurate, non-invasive, cost-effective technique for examination of the soft tissue and osseous structures of the knee. The purpose of this study was to evaluate the accuracy of low-field MRI by comparing the results with subsequent arthroscopy.
  
  
  METHODS
  MR imaging study of 146 patients was done using 0.25 T ESTOATE G-SCAN and the sequence used were SE, FSE and GRE in all the three planes. The comparison was based on five parameters: accuracy, sensitivity, specificity, positive predictive value, and negative predictive value.
  
  
  RESULTS
  Our study showed high accuracy (98.08%) and negative predictive value (98.62%) for MRI in comparison with arthroscopy.
  
  
  CONCLUSIONS
  Low-field MRI alleviates the need of arthroscopy for detection of meniscus tears and ligament tears.
