ABSTRACT
OBJECTIVE:
To investigate (a) which MR features of inflammation (synovitis, tenosynovitis, perfusion) correlate with clinical/serological features in early rheumatoid arthritis (ERA) before, during and after 1 year of treatment and (b) whether quantitative or semi-quantitative measures of inflammation on magnetic resonance imaging (MRI) provides the highest correlation in this regard.METHOD:
One hundred one ERA patients (76 females, 25 males, mean age, 53 ± 12 years) underwent clinical/serological testing and 3 T dynamic contrast-enhanced MRI of the most symptomatic wrist. Seventy-seven of the 101 patients completed 1 year of treatment, followed by repeat MR examination. Clinical/serological parameters were correlated with semi-quantitative/quantitative MR measures of inflammation at baseline, during and after 1 year of treatment. Spearman's correlation was applied.RESULTS:
Quantitative measures of inflammation correlated better with clinical/serological parameters than semi-quantitative measures, with the highest correlations being for relative change during treatment. Pain reduction correlated with reduced tenosynovitis volume (r = 0.41). Reduction in disease activity correlated with reduction in synovitis volume (r = 0.66) or synovial perfusion parameters (r = 0.58). Decrease in early morning stiffness correlated with decrease in perfusion parameters (r = 0.46). Reduction in ESR and CRP correlated with decrease in synovial volume (r = 0.40 and r = 0.41, respectively).CONCLUSION:
In ERA patients, quantitative assessment of inflammation on MRI correlated better with clinical parameters than semi-quantitative assessment. Relative change during treatment yielded the highest correlation. Decrease in tenosynovitis correlated best with reduction in pain while decrease in synovitis volume and perfusion correlated best with reduction in disease activity, early morning stiffness (perfusion), or serological parameters (synovitis volume).Palavras-chave
