Condition
Prostate cancer
Intervention
Patients will be randomised to receive either 50kBq/kg or 80kBq/kg of radium 223. Patients in both arms will receive radium-223 every 4 weeks for up to 6 treatments. Follow up will be from 4 weeks after the last administration of radium-223. Patients will be evaluated every four months until 1 year after last administration.

Primary outcome measures
The proportion of patients showing bone metastases response on diffusion weighted MRI (DW-MRI). From pre-treatment to any point after 1st injection and the end of cycle 6 will be used to define response.
