This website is designed to promote diagnostic imaging and treatment of arthritides predominantly affecting the sacroiliac and spinal joints.

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 easy accessible images showing typical disease manifestations and normal findings at MRI.

The overall purpose of this website is to illustrate and describe the typical findings at MRI in patients with AS corresponding to different degrees of disease severity. Moreover, to show MR changes in other forms of SpA and changes that may be misinterpreted as arthritis in addition to normal findings. Doctors who use MRI to diagnose and monitor AS can easily acquire knowledge promoting optimal use of MRI.
Patients should have the opportunity to acquire knowledge about the diagnostic and monitoring possibilities by MRI which constitute the backbone of their diagnosis and treatment.
To increase reader-friendliness and applicability this website offers explanations of medical terminology.
