Magnetic resonance imaging (MRI) is increasingly used to confirm the diagnosis of ankylosing spondylitis (AS), also named Morbus Bechterew, and other forms of arthritides predominantly affecting the sacroiliac and spinal joints, collectively named spondyloarthropathies (SpA). MRI is also suitable for monitoring these rheumatic diseases. It is important for the use of MRI to detect and follow AS that the interpretation of the findings is certain and uniform between the departments performing MRI. To ensure this, there is a need for easily accessible images showing typical disease manifestations and normal findings at MRI. |
