Session Type: ACR Poster Session A
Session Time: 9:00AM-11:00AM
Background/Purpose: The aim of the study was to evaluate a simplified version of the Rheumatoid Arthritis Magnetic Resonance Imaging Score (RAMRIS) to five joints of the hand (RAMRIS-5) in patients with early rheumatoid arthritis (RA) before and after the initiation of a methotrexate (MTX) therapy using high-resolution, 3 Tesla (T), magnetic resonance imaging (MRI).
Methods: 28 RA patients according to 2010 ACR/EULAR criteria (Ø 56.8 years (range 39 – 74), seropositive, disease duration < 6 months (range 2 – 23 weeks) were prospectively assessed with baseline investigation including clinical assessment (DAS-28 and CRP) and 3T MRI of the clinical dominant hand, as well as 3 and 6 months after starting MTX therapy. MRI-scans were analysed according to RAMRIS and the simplified RAMRIS-5 (Figure-1).
Results: DAS-28, CRP, RAMRIS and RAMRIS-5 decreased significantly after initiation of a MTX therapy. There was a strong correlation between RAMRIS-5 and RAMRIS at baseline (r=0.838; p=˂0.001) and follow-up (3 months: r=0.876; p= ˂0.001; 6 months: r=0.897; p=˂0.001).
Conclusion: 3T MRI based RAMRIS-5, a simplified and resource-saving RAMRIS score is a suitable tool to show changes in early RA and may be used for diagnosis and therapy monitoring in follow-up evaluations.
