How does arthritis show up on MRI?

Arthritis can be detected on MRI through various features such as joint effusion, bone marrow edema, cartilage degeneration, and the presence of osteophytes. In inflammatory arthritis, like rheumatoid arthritis, MRI may also show synovial thickening and enhancement. Additionally, MRI can reveal subchondral bone changes and joint deformities, providing a detailed view of the extent of the disease. This imaging technique helps assess both structural damage and inflammation in the joints.
