Age minimum: 18 Years
Age maximum: 80 Years
Gender: Both

Health Condition(s) or Problem(s) studied

Rheumatoid Arthritis

Intervention(s)

Drug: Methotrexate

Drug: Infliximab

Primary Outcome(s)

Changes in the volume of enhancing synovitis measured by Magnetic Resonance Imaging(MRI) as it corresponds to active, inflamed tissue and is therefore expected to be a better marker of disease activity. [Time Frame: week 24]

Secondary Outcome(s)

Correlation between the Magnetic Resonance Imaging(MRI) findings and changes on x-ray [Time Frame: week 24]

proportion of patients achieving ACR and EULAR responses [Time Frame: week 24]

changes in the synovitis grading and the perfusion indices [Time Frame: 24 week]
