Radiology has a small case series about using MRI-guided focused ultrasound to treat painful bone metastases. It works exactly how it sounds. It requires conscious sedation and was done on an outpatient/same-day basis. This study is a small case series (n=11) of patients with persistently painful bone mets who had failed routine treatments, including external beam radiotherapy. Average pain decreased from ~6/10 at baseline to ~4/10 at day 2 and 2/10 two weeks out. Of course this is an uncontrolled case series and patients were presumably being treated with other modalities.
