What is the prognostic value of myocardial perfusion imaging using rubidium-82 positron emission tomography?
Myocardial perfusion imaging using rubidium-82 positron emission tomography (PET) has been shown to have prognostic value in multiple studies. Specifically, a 2006 study by Yoshinaga et al. found that using rubidium-82 PET, they were able to accurately identify patients at risk for cardiac mortality. Furthermore, a 2008 study by Lertsburapa et al. showed that it had independent and incremental prognostic value in patients with known or suspected coronary artery disease.
