Cardiac MRI for Metal on Metal Hip Resurfacing

Cardiac MRI is used to assess cardiac function in patients at risk of cardiotoxicity. In addition, Cardiac MRI enables imaging of inflammation, and fibrosis in the heart which may provide more specific information about the mechanism of injury in patients with high ion blood levels. Patients in all three groups (Unilateral hip resurfacing, bilateral hip resurfacing, and non-metal on metal total hip arthroplasty) will undergo a Cardiac MRI.
