RT Journal Article SR Electronic T1 Myocardial Perfusion Imaging with 201Tl JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 1 OP 3 DO 10.2967/jnmt.109.068593 VO 38 IS 1 A1 Pagnanelli, Robert A. A1 Basso, Danny A. YR 2010 UL http://tech.snmjournals.org/content/38/1/1.abstract 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.
