Aim #1 - To determine if PDS can be used to diagnose synovial hypertrophy and inflammation in joint disease associated with inherited bleeding disorders. MRI will be used as a reference standard.~Aim #2 - To determine if PDS can be used to assess therapeutic response to treatment.~Aim #3 - To determine if PDS can be used as a screening tool for diagnosing early synovitis.
The purpose of this study is to see whether power Doppler sonography (PDS) can be used to diagnose synovitis in patients with inherited bleeding disorders.
