Nuclear medicine
Nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear medicine scans are usually conducted by radiographers. Nuclear medicine, in a sense, is ""radiology done inside out"" or ""endoradiology"" because it records radiation emitting from within the body rather than radiation that is generated by external sources like X-rays.
