  "field": "Oncology and biomedicine",
  "definition": "A radioconjugate composed of the chelating agent and bone seeking agent diethylenetriaminepentaacetic acid (DTPA) complexed to the radionuclide tin (Sn) 117m (stannic, 4+), with potential use as a palliative agent for bone pain from bony metastases. Upon administration of Sn-117m-DTPA, the DTPA localizes to bones, thereby leading to the accumulation of the radioactive agent in bone. The radiation may destroy tumor cells in bone metastasis and may alleviate the pain.",
