Focused ultrasound

Uptodate 2015

Magnetic resonance guided focused ultrasound is an approved technique to provide palliation for painful bone metastases in patients who have either failed on standard radiation therapy (RT) or are not candidates for RT. The focused ultrasound waves raise the temperature at the imaged focal point and thus produce thermal tissue ablation.

The regulatory approval of this device was based upon an international multicenter trial that demonstrated the activity and safety of this approach [22].
