Efforts to visually match 5- and 60-minute post-stress images following a single injected dose of sestamibi clearly demonstrate changes in sestamibi distribution: Demonstrating once and for all clinical recognition that sestamibi redistributes

Importance: Sestamibi imaging has been available for approximately three decades. During that time there has been considerable evidence published in the medical literature demonstrating that Sestamibi redistributes. Despite these publications, Lantheus has continued to insist that Sestamibi does not redistribute and that two doses of radioactive isotope are needed to conduct myocardial perfusion imaging. Isotope package inserts have maintained that Sestamibi is initially taken up by the heart within minutes without redistribution making it not only possible but acceptable to wait until 60-minutes to begin imaging. This approach then requires a second dose of Sestamibi to acquire comparative images for clinical decision-making according to the Sestamibi package insert.
