aACW = anterior chest wall; AS = ankylosing spondylitis; MSJ = manubriosternal joint; nrSpA = nonradiographic axial spondyloarthritis; SClJ = sternoclavicular joint; SCoJ = sternocostal joint; SpA = spondyloarthritis. bBone marrow edema ACW and/or erosion ACW, fat infiltration ACW, synovitis SClJ, fusion MSJ. The number of patients with MRI-detected lesions in the entire ACW may be lower than the addition of patients with MRI changes of the three joints SClJ, MSJ and SCoJ, because some patients showed inflammation in more than one joint. Values are the number of subjects (percentage). |
