چکیده

The biodistribution of 227Th-EDTMP and retention of its daughter nuclide 223Ra were examined. 227Th-EDTMP was found to show high uptake and long-term retention in bone. The clearance of 227Th-EDTMP from blood and soft tissues was rapid and the femur-to-tissue uptake ratios reached more than 100 within 30 min for all tissues except the kidney. Seven and 14 days after injection of 227Th-EDTMP, the retention index of 223Ra in bone showed high values, and the differences between these time points were not significant. Therefore, 227Th-EDTMP is a potential radiotherapeutic agent for bone metastasis.
