OBJECTIVE: To assess the usefulness of MRI as a diagnostic method in patients with rheumatoid arthritis, and to evaluate the frequency of changes in the hip in symptomatic and asymptomatic patients. MATERIALS AND METHODS: Forty patients (17 symptomatic and 23 asymptomatic) were evaluated by 1.5 T magnetic resonance imaging (MRI) after intravenous contrast media injection. MRI findings were divided in inflammatory, degenerative, combined (inflammatory and degenerative) and extra-articular changes. RESULTS: The most frequent findings seen were degenerative and extra-articular changes (22.5% each). Inflammatory changes were seen in only five (12.5%) symptomatic patients, four of them with degenerative findings associated (10%). CONCLUSION: The use of MRI of the hip allowed the evaluation of the main articular abnormalities seen in patients with rheumatoid arthritis. The most frequent findings were degenerative and extra-articular changes. Inflammatory findings were seen in only five patients, four of them with degenerative changes associated.
