INTRODUCTION: Established radiotracers for positron emission tomography (PET) myocardial perfusion study are commonly labeled with short-lived radio-isotopes that limit their widespread clinical use. Thus, we synthesized (2-(2-[(18)F]fluoroethoxy)ethyl)tris(4-methoxyphenyl)phosphonium salt ([(18)F]FETMP) as a novel myocardial perfusion agent that penetrates the hydrophobic barriers of the plasma and mitochondrial membranes and accumulate in mitochondria ...

Cardiovascular disease is the leading cause of global mortality, yet its early detection remains a vexing problem of modern medicine. Although the computed tomography (CT) calcium score predicts cardiovascular risk, relatively high cost ($250-400) and radiation dose (1-3 mSv) limit its universal utility as a screening tool. Dual-energy digital subtraction ...
