[Abstract] Objective: To investigate the clinical value of assessing the activity of rheumatoid arthritis using revised MRI scoring system.Materials and Methods: MR images of both wrists and the 2nd to 5th metacarpophalangeal joints of 77 patients with RA were analyzed. MRI scores of each patient were acquired using a revised OMERACT RAMRIS Scoring System, which was based on initial OMERACT RAMRIS Scoring System and added the scores of the proximal interphalangeal joints, distal interphalangeal joints and tenosynovistis.The intra- and inter-reader reliability of MRI scoring system was assessed. The relationships between MRI score of each sign, between MRI score and clinical data were analyzed respectively.Results: There was a significant correlation between MRI total score and CRP (r= 0.322, P=0.009), ESR (r=0.406, P=0.001), between bone edema score, tenosynovitis score and CRP (r=0.348 and 0.414, P=0.017 and 0.004), between tenosynovitis score and the number of pain joints (r=0.329, P=0.013), between synovitis score and bone erosion score (r=0.542, P=0.000), bone edema score (r=0.365, P=0.001), tenosynovits score (r=0.610, P=0.000), between bone erosion score and bone edema score (r=0.543, P=0.000), tenosynovitis score (r=0.430, P=0.000), between bone edema score and the tenosynovitis score (r=0.671, P=0.000).Conclusion: The revised MRI scoring system can be used to assess the activity of RA semi-quantitatively and play an important role in clinical study. |
