Samarium-153?(Sm-153) is a radioisotope used in metabolic radiation therapy for the treatment of pain from bone metastases. It is produced in nuclear reactors, by neutron irradiation of samarium-152 (Sm-152 Sm2O3).
Samarium-153 decays by emitting both beta minus particles and gamma photons with a characteristic gamma peak of 103.2 KeV; it has a physical half-life time of 1.93 days. The carrier molecule used is the ethylene diamine tetramethylene phosphonate acid (EDTMP), a chelator osteotropic tetraphosphonate. The radiopharmaceutical Sm-153 EDTMP (dose: 37 MBq/Kg) shows a biodistribution similar to that of technetium-99m methylene diphosphonate (Tc-99m MDP).?The gamma (photons) component also allows the use of the radiotracer for nuclear medical imaging (follow-up).
