Radiopharmaceuticals for therapy

Radionuclide therapy (RNT) using radiopharmaceutical based on the concept of delivering cytotoxic levels of radiation to specific disease sites for cure, disease control or pain palliation, is one of the rapidly growing fields of nuclear medicine. RNT targets diseases at the cellular level and offers the scope of delivering radiation directly to the disease site with potentially less exposure to the normal tissues. This concept is a blend of a tracer moiety that mediates a site specific accumulation followed by induction of cytotoxicity with the short-range biological effectiveness of particulate radiations
