The primary purpose of this study is to see if MR guided high intensity focused ultrasound (MR-HIFU) treats bone pain faster than the standard radiation therapy (External beam radiation therapy: EBRT) and to evaluate the patient's pain experience 14 days after completion of the treatment. The secondary purpose is to evaluate the outcomes of the pain, side effects, and quality of life and survival in the first 6 months after treatment.
This is a prospective, single-center, randomized study directly comparing outcomes after MR guided high intensity focused ultrasound (MR HIFU) or external beam radiation therapy (EBRT) treatment of painful bone metastases.
