• A Phase III Multi-Center Randomized Controlled Trial to Compare the Effectiveness of Magnetic Resonance guided Focused Ultrasound with Computed Tomography Guided Radiofrequency Ablation for Treatment of Osteoid Osteomas Rochester, Minn.

  The purpose of this study is based on the premise that MRgFUS is noninferior to CT-guided radiofrequency ablation (CTgRFA), in terms of pain reduction following treatment of osteoid osteomas, and offers possible improvements with regards to post-procedural pain, clinical resource utilization, patient experience, and/or adverse events. The data from the current study would provide clinicians important information in deciding between treatment options for ablation of osteoid osteomas.
