Assistant: Technetium Tc-99m tetrofosmin is a drug used in nuclear myocardial perfusion imaging. The radioisotope, technetium-99m, is chelated by two 1,2-bis[di-(2-ethoxyethyl)phosphino]ethane ligands which belong to the group of diphosphines and which are referred to as tetrofosmin. It is a lipophilic technetium phosphine dioxo cation that was formulated into a freeze-dried kit which yields an injection. Technetium Tc-99m tetrofosmin was developed by GE Healthcare and FDA approved on February 9, 1996.
