Abstract
Objective: To validate reliability, correlation and responsiveness of two whole-body MRI scores for the hip/pelvis region in spondyloarthritis. Methods: Assessment of hip/pelvis inflammation in 4 multi-reader exercises using the OMERACT MRI Whole-body score for Inflammation in Peripheral joints and Entheses (MRI-WIPE) and Hip Inflammation Magnetic Resonance Imaging Scoring System (HIMRISS). Results: In exercises 3–4 (11/20 cases, respectively; 9 readers) reliability was mostly good for the 3 best calibrated readers. Median pairwise single-measure ICC for status were 0.58–0.65 (WIPE-osteitis), 0.10–0.88 (HIMRISS-osteitis) and for status/change 0.38–0.72/0.52–0.60 (WIPE-synovitis/effusion) and 0.68–0.89/0.78–0.85 (HIMRISS-synovitis/effusion). SRM was 1.23 for WIPE-osteitis, while lower for WIPE-synovitis/effusion and HIMRISS. Conclusion: MRI-WIPE and HIMRISS may after further validation be useful in future spondyloarthritis trials.
