Osteoid osteoma is currently most frequently treated with CT guided radiofrequency ablation (CTgRFA), which is effective, but invasive and exposes the typical young patient population with osteoid osteomas to radiation. Our preliminary results are presented describing MR guided focused ultrasound (MRgFUS) for the treatment of patients with osteoid osteomas. As also reported in two European studies, in our experience, MRgFUS is effective at eliminating pain in these patients. These data form the basis for a proposed clinical trial directly comparing the safety and efficacy of MRgFUS and CTgRFA for treatment of osteoid osteoma.
