Effective diagnosis of ankylosing spondylitis (AS) activity plays an important role for clinical treatment and prognosis. In our study, we used intravoxel incoherent motion (IVIM) and dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) to differentiate the active and chronic stage of AS. As a result, we found that D_slow, K^trans and V_e had a high diagnostic sensitivity and specificity.
