Overview
MRI may be helpful in the diagnosis of ankylosing spondylitis. Findings on MRI suggestive of ankylosing spondylitis include sacroiliitis, disease activity,cartilage condition and enthesitis.MRI allows assessment of all of the structures that are involved in musculoskeletal diseases.MRI is more sensitive in inflammatory and degenerative rheumatological disorders.However, not all patients with nr-axSpA have abnormal MRI findings.
MRI Scan
- Findings on MRI suggestive of ankylosing spondylitis include:[1][2][3][4]
- Helps in diagnosis of active sacroiliitis.
- Helps in diagnosis of enthesitis/ capsulitis.
- Helps in detection of bone marrow edema (BME).
- Helps in detection of fat metaplasia.
- helps in detection of
- Cartilage inflammation and destruction.
- Bone erosions
- Subchondral bone changes
