Feasibility of Combined Focused Ultrasound and Radiotherapy Treatment in Patients With Painful Bone Metastasis

Following standard EBRT (single or multiple fraction), patients will receive one MR-HIFU treatment with the Profound Sonalleve MR-HIFU device on the most painful of their bone metastases. This treatment will take place in a short time frame of 3 hours to maximum 4 days. Patients will be followed up until 4 weeks after treatment. During follow-up they will be phoned around day 3, 7, 14, 21 and 28 to retrieve pain scores, pain medication and (serious) adverse events. At day 3 the patient's experience with the combined treatment will also be inquired.
