THE CLINICAL VALUE OF USING MRI IN DIAGNOSINGPIGMENTED VILLONODULAR SYNOVITIS

Objective To explore the clinical value of using magnetic resonance imaging(MRI) to diagnose pigmented villonodular synovitis.Methods The MRI results of 12 cases of pigmented villonodular synovitis confirmed by surgery and pathology were analyzed.Results 8 cases were sporadic,4 cases multiple,10 cases diffusive and 2 cases of focal with T1WI low signals or T2WI mixed signals.Conclusion MRI can clearly show the shape and range of pigmented villonodular synovitis.
