Choice of Radionuclides for Scintigraphy,s places some constraint on the type of substance to be labelled, but more importantly on the radionuclide to be employed as the radiolabel. The agents are normally administered at low concentrations and low frequency (often only once) and the radionuclides commonly employed in scintigraphy are eith

Conventionally, radiopharmaceutical agents are products in which a radionuclide label is formulated in such a way as to cause it to localise in some organ or lesion. Once localised, the externally detectable radiation may be displayed to produce clinically useful diagnostic information, and
