Abstract
Objectives
To assess the value of magnetic resonance imaging (MRI) in discriminating between active and inactive juvenile idiopathic arthritis (JIA) patients and to compare physical examination outcomes with MRI outcomes in the assessment of disease status in JIA patients.
Methods
Consecutive JIA patients with knee involvement were prospectively studied using an open-bore MRI. Imaging findings from 146 JIA patients were analysed (59.6 % female; mean age, 12.9 years). Patients were classified as clinically active or inactive. MRI features were evaluated using the JAMRIS system, comprising validated scores for synovial hypertrophy, bone marrow oedema, cartilage lesions and bone erosions.
Results
Inter-reader reliability was good for all MRI features (intra-class correlation coefficient [ICC] = 0.87–0.94). No differences were found between the two groups regarding MRI scores of bone marrow oedema, cartilage lesions or bone erosions. Synovial hypertrophy scores differed significantly between groups (P = 0.016). Nonetheless, synovial hypertrophy was also present in 14 JIA patients (35.9 %) with clinically inactive disease. Of JIA patients considered clinically active, 48.6 % showed no signs of MRI-based synovitis.
Conclusions
MRI can discriminate between clinically active and inactive JIA patients. However, physical examination is neither very sensitive nor specific in evaluating JIA disease activity compared with MRI. Subclinical synovitis was present in >35 % of presumed clinically inactive patients.
Key points
• MRI is sensitive for evaluating juvenile idiopathic arthritis (JIA) disease activity.
• Contrast-enhanced MRI can distinguish clinically active and inactive JIA patients.
• Subclinical synovitis is present in 35.9 % of presumed clinically inactive patients.
• Physical examination is neither sensitive nor specific in evaluating JIA disease activity.
