What is the prognostic value of myocardial perfusion imaging using rubidium-82 positron emission tomography?
Rubidium-82 positron emission tomography (PET) is a form of myocardial perfusion imaging that has been shown to have prognostic value in patients with known or suspected ischemic heart disease. Studies have demonstrated that it is able to provide independent and incremental prognostic value in terms of predicting cardiac mortality, as well as risk stratifying individuals with suspected coronary artery disease. It has also been shown to have gender-specific prognostic value, with different normal limits and outcomes in women compared to men.
