Abstract
Positron emission tomography (PET) is a radionuclide imaging technique that allows for noninvasive quantification of biochemical pathways in vivo. Utilizing positron emitting labelled compounds of interest, a myriad of biological processes can be visualized in the human heart. As such, PET has been proven invaluable to the noninvasive investigation of cardiovascular biology and physiology. Assessment of myocardial perfusion and substrate metabolism are of particular value in the evaluation of patients with (suspected) coronary artery disease (CAD) to detect ischemia and myocardial viability. This chapter will outline the fundamental principles of PET and technical considerations of cardiac PET imaging.
