Thallium TL-201 is a radioactive isotope of thallium with a half-life of 73 hours. As a chloride salt, it is used in myocardial perfusion imaging for diagnosis and localization of myocardial infarction. In conjunction with exercise stress testing, thallium TL-201 injection is used in the diagnosis of ischemic heart disease. However, technetium-99m sestamibi and Tc-99m tetrafosmin have supplanted thallium-201 chloride as the most commonly used single-photon myocardial imaging agents, because of their superior image quality and the lower effective radiation dose to the patient.
