Radiopharmacology or medicinal radiochemistry is radiochemistry applied to medication and subsequently the pharmacology of radiopharmaceuticals. Radiopharmaceuticals are utilized as a part of the field of nuclear prescription as radioactive tracers in medical imaging and in treatment for some diseases (for instance, brachytherapy). Numerous radiopharmaceuticals use technetium-99m (Tc-99m) which has numerous valuable properties as a gamma rays-emitting tracer nuclide. In the book Technetium an aggregate of 31 distinct radiopharmaceuticals in light of Tc-99m are recorded for imaging and useful investigations of the mind, myocardium, thyroid gland, lungs, liver, gallbladder, kidneys, skeleton, blood and tumours.

The term radioisotope, which in its general sense alludes to any radioactive isotope (radionuclide), has verifiably been utilized to allude to all radiopharmaceuticals, and this utilization stays basic. In fact, however, numerous radiopharmaceuticals consolidate a radioactive tracer atom into a bigger pharmaceutically-active molecule, which is localized in the body, after which the radionuclide tracer atom permits it to be effortlessly recognized with a gamma camera or comparable gamma imaging device. N example is fludeoxyglucose in which fluorine-18 is fused into deoxyglucose. A few radioisotopes (for instance gallium-67, gallium-68, and radioiodine) are utilized straightforwardly as dissolvable ionic salts, without further alteration. This utilization depends on the chemical and biological properties of the radioisotope itself, to restrict it within the body.
