OBJECTIVE: To evaluate magnetic resonance imaging (MRI) guided corticosteroid injections of inflamed sacroiliac (SI) joints in patients with spondyloarthropathy with therapy resistant sacroiliitis. METHODS: We performed 16 injections in 9 patients on an outpatient basis (6 men, 3 women, mean age at onset 24.7 +/- 7.5 yrs). All patients had MRI guided injection of 40 mg triamcinolone acetonide into SI joints using an open 0.2 Tesla unit. Before and 3 months after corticosteroid injection they underwent an MRI examination with a closed 1.5 Tesla unit. RESULTS: Seven of 9 patients reported subjective improvement that lasted at least a mean of 10.8 +/- 5.6 months. Subchondral bone marrow edema on fat suppressed images resolved in 8 patients after corticosteroid injection. CONCLUSION: MRI guided corticosteroid injection of SI joints appears to be an effective and safe procedure without exposure to radiation. It is a useful therapeutic modality, especially in young patients with severe isolated sacroiliitis.
