The OMERACT Psoriatic Arthritis Magnetic Resonance Imaging Score (PsAMRIS) Is Reliable and Sensitive to Change: Results from an OMERACT Workshop

Abstract

This multireader exercise, performed under standardized conditions, confirmed PsAMRIS to have high interobserver and intraobserver reliability for hand PsA. Measures of inflammation were sensitive to change, implying that PsAMRIS may be a valuable tool for monitoring change in inflammation during PsA clinical trials.
