Imaging in ankylosing spondylitis
Radiographs and magnetic resonance imaging (MRI) for sacroiliac (SI) joints and the spine are the most important imaging techniques for the diagnosis and followup of patients with spondyloarthritis (SpA), including response to treatment. If other sites outside the axial skeleton are affected they can also be investigated by these methods. In general, radiographs should not be performed more frequently than every 2 years because (chronic) changes occur slowly and investigations with MRI can be used more frequently, according to the clinical situation.
