Radionuclide scanning uses the radiation released by radionuclides called nuclear decay to produce images a radionuclide is an unstable isotope that becomes more stable by releasing energy as radiation this radiation can include gamma ray photons or particulate emission such as positrons used in pet. Basic principles of radionuclide imaging an in depth review of the techniques of radionuclide imaging is beyond the scope of this chapter a brief overview is presented here radionuclide imaging begins with the administration of a radiolabelled tracer the tracer contains a radioactive isotope bound to a complex or molecule which determines .
