Overview

MRI may be helpful in the diagnosis of hemophilia. Findings on MRI suggestive of hemophilic arthropathy include effusion, synovial hyperplasia, erosion, subchondral cyst, cartilage loss, osteonecrosis, fibrocartilage tear, ligament tear, loose body.

MRI

The additive European MRI scoring system[1]
