Abstract: HTML Purpose: To evaluate the role of magnetic resonance (MR) imaging in evaluating psoriatic arthropathy Methods and Materials: Sixteen patients (M:F=11:5, mean age 45.9 yrs) with active psoriatic arthropathy (wrist 6, hand 5, knee 3, foot 2) who had positive findings on plain radiographs were analyzed. MR images were obtained on at least two orthogonal planes and each examination included at least one FSE T2, gadolinium-enhanced T1 with fat saturation, and 3D gradient sequences. Using our home-developed scoring system, bone marrow edema, bone erosion, synovial proliferation, joint effusion, bone proliferation/ enthesopathy, and para-articular soft tissue change were evaluated and scored for the T2 signal intensity, the degree of enhancement, and extent. A four-point scale of 0 to 3 was. American College of Rheumatology (ACR)s clinical scoring system (a 4 point scale) was used for pain and swelling assessment. The score sum of each MR finding was compared with the clinical score. Four musculoskeletal radiologists evaluated the images by consensus and 1-tail paired t-test was used for statistical analysis. Results: Synovial proliferation and bone erosion were observed in all 16 cases. Bone marrow edema was found in 83%, para-articular soft tissue change and bone proliferation were found in 63% and joint effusion was present in 56% of cases. BM edema, bone erosion, and synovial proliferation showed a significant correlation with patients pain score, swelling score, and combined score. Joint effusion and bone proliferation did not have a significant correlation with clinical disease severity. Conclusion: MR can be a useful imaging modality for psoriatic arthritis and may be used for a semi-quantitative assessment using our scoring system.     (G.S. received a grant from Mgen.)
