The new Assessment of SpondyloArthritis international Society (ASAS) criteria classify axial spondyloarthritis (SpA) into human leucocyte antigen-B27 and/or imaging-based arms. To aid implementation, ASAS has proposed a definition of a positive MRI for active sacroiliitis. ⋯ Both arms of the ASAS criteria have good diagnostic utility in early SpA, although they are of limited value for the prediction of radiographic progression. This may be due to the definition of a positive MRI for sacroiliitis that lacks specificity at baseline.
