Multicenter evaluation of low-field MRI as a tool for monitoring treatment response in patients with rheumatoid arthritis (RA) on the REMISSION PLUS pilot project.


RA patients initiating treatment with a DMARD or biologic at 9 sites throughout Germany underwent low-field MRI (C-scan, Esaote, 0.2 T) of the clinically dominant hand at time points T0 (baseline), T1 (3 months) and T2 (6 to 12 months). The images were evaluated semiquantitatively using the RAMRIS scoring system and correlated with clinical and lab chemistry markers.


206 RA patients (T0), 58 = m, 148 = f, age (years): (mean=55.87, min.19, max. 84), time since diagnosis: (median=20.32 months, min. 0.2 months, max. 45 years), DAS28 (mean = 4.83, 2.1 – 8), rheumatoid factor positive n = 118, CCP antibody positive n = 118, treatment naive: n = 64, switching treatments: n = 187; MRI follow-up at 3 months (T1) and at 6 to 12 months (T2); T0 and T2: n=96; T0, T1 and T2: n=55. RAMRIS (T0-T1-T2): 41.58-29.62-21.91; MCP: 13.31-8.76-6.38; wrist: 28.19-20.74-15.50; synovitis score (MCP): 5.11-3.06-1.60; wrist: 4.47-3.64-2.54; edema score (MCP): 2.85-1.74-0.91; wrist: 10.04-5.60-2.91; erosion score (MCP): 5.35-4.13-3.87; wrist: 13.68-11.49-10.06; SRM (standardized response mean (> 0.5 moderate potential to detect changes)) T0-T2 synovitis: 0.999 (MCP); 0.709 (wrist), edema: 0.702 (MCP); 0.792 (wrist); p-correlations T0-DAS28 for synovitis: 0.010 (MCP); 0.037 (wrist); for edema: 0.507 (MCP); 0.049 (wrist); T0-CRP for synovitis: 0.538 (MCP); 0.276 (wrist); for edema: 0.154 (MCP); 0.011 (wrist).


Low-field MRI is a sensitive imaging method and RAMRIS a practicable scoring system for morphological and semiquantitative evaluation of therapeutic response to real-life rheumatologic care in significant correlation to clinical and lab data. The added benefit of low-field MRI is that it provides in-depth information on the severity of synovitis, edema (significant reduction on treatment) and erosion during follow-up, hence enabling early identification of responders/non-responders and providing a basis for individual prediction of prognosis and optimal disease management.
