Bifunctional Chelators for Technetium-99m
1996Technetium-99m has nearly optimal characteristics as a radionuclide for diagnostic radiopharmaceuticals: (1) a low radiation dose to the patients due to the absence of a-and β-radiation and the short physical half-life (6.02 h), (2) the excellent quality of its scintigraphic images as a result of the favourable energy of its gamma radiation (140.5 keV)

Technetium-99m Diphosphonate Retention in Hyperparathyroidism
Annals of Internal Medicine, 1980Excerpt To the editor: Fogelman and colleagues (1) show increased total-body retention of technetium-99m diphosphonate in a small group of patients with primary hyperparathyroidism and equate this ...

Newer Technetium-99m Radiopharmaceuticals
1987Just now, we are having the semicentenary of the discovery of the element 43, later on named “technetium” (1,2). In 1937, Perrier and Segre showed that radioactive isotopes of element 43 could be formed by neutron or deuteron bombardment of molybdenum. They investigated the activity in order to collect some information on the chemistry of 43.

Technetium‐99m radiochemistry for pharmaceutical applications
Journal of Labelled Compounds and Radiopharmaceuticals, 2017Technetium‐99m (99mTc) is a widely used radionuclide, and the development of 99mTc imaging agents continues to be in demand. This overview discusses basic principles of 99mTc radiopharmaceutical preparation and design and focuses on the 99mTc radiochemistry relevant to its pharmaceutical applications. The 99mTc complexes are described based on the most

Labelling Methods with Technetium-99m
1987Technetium-99m has favourable physical radiation characteristics (halflife = 6.02 h, nearly pure gamma radiation of 140 keV energy) and is distributed as Mo-99/Tc-99m generators to most nuclear medicine departments or radiopharmacy units. Though its radiation is simple, its chemistry is complicated and induces numerous pharmaceutical problems.
