Nucl. Med. Technol.2010 Mar 01; 38 AB - The object of this review is to provide information about 201Tl-thallous chloride in radionuclide myocardial perfusion imaging. This technique has experienced a recent resurgence because of the shortage of 99mTc. After reading this article, the technologist will be able to describe the properties and uptake mechanism of 201Tl, the procedure for myocardial perfusion imaging with this agent, and the advantages and disadvantages of thallium, compared with the technetium agents.
