SECONDARY outcome

Timeframe: Baseline, 3 months and 6 months

Alkaline phosphatase reduction to quantitative imaging techniques (99mTc-MDP, 18FDG-PET-CT, 18FNa PET-CT scans) to determine objective response of osteosarcoma indicator lesions to 223-radium dichloride. \>30% increase in SUV peak indicates progression, if \>30% decrease in SUV peak indicates a response and other does not meet above criteria or mixed response using the NAFCIST and PERCIST criteria.
