Figure 1: Schematic of the uptake mechanisms of the principal cardiac PET radiotracers used for the assessment of myocardial blood flow (MBF) (15O-water, 13N-ammonia, 82Rubidium, 11C-Acetate) and metabolism (18F-FDG, 18F-FTHA, 11C-Palmitate, 11C-Acetate and 11CAcetoacetate). Fluorodeoxyglucose (FDG), Glucose transporters (GLUT), 18-fluorodeoxyglucose-6-phosphate (18F-FDG-6-P), Monocarboxylate transporter (MCT), 14(R,S)-Fluoro-6-Thia-Heptadecanoic Acid (FTHA), Fatty acid transport protein (FATP).
