Spondyloarthritis (SpA) is an inflammatory rheumatic disease and hip involvement often results in severe deformities and functional impairment. Magnetic resonance imaging (MRI) is a powerful imaging tool for detecting early hip lesions in SpA. The aims of this study are to apply the hip inflammation MRI scoring system (HIMRISS) in SpA patients and to evaluate its reproducibility and validity. ⋯ HIMRISS offers a reliable MRI scoring method for hip joint in SpA, and it is beneficial for early detection and fast quantification in disease activity assessment.
