Overview
The findings on MRI in a patient with ankylosing spondylitis is synovial enhancement. It is superior to CT in detection of cartilage, bone erosions, and subchondral bone changes. An increased T2 signal correlates with edema or vascularized fibrous tissue.
MRI
- May have a role in early diagnosis of sacroiliitis
- Synovial enhancement on MR correlates with disease activity measured by inflammatory mediators
- Superior to CT in detection of cartilage, bone erosions, and subchondral bone changes
- Increased T2 signal correlates with edema or vascularized fibrous tissue
- Useful in following treatment results in patients with active ankylosing spondylitis
