Abstract
Bone scanning or scintigraphy is directed towards identifying sites of altered skeletal metabolism and abnormal foci of calcium phosphate deposition, such as heterotopic ossification and soft tissue calcification. The requirements of an ideal bonescanning agent are excellent imaging properties of the nuclide, high concentration of the nuclide at the abnormal site, little or no extraosseous or noncalcification site uptake, minimum tissue radiation, simple and safe preparation of the agent and ready availability of the nuclide. No scanning agent has all these ideal characteristics but the 99mTc diphosphonates come closest to satisfying the above criteria. 99mTc is easily obtained from a molybdenum-99/technetium-99m generator. The scheme, abundances, half-lives and energies are shown in Fig. 2.1.
