Objectives Positron emission tomography (PET) with 18F-FE-PE2I is useful for investigating the function of dopamine transporter, and kinetics of 18F-FE-PE2I could be described by standard two-tissue compartment model (2CM) using plasma input function. In this study, we investigated the feasibility of semi-quantitative methods for estimating binding potential (BPND) and transporter occupancy to shorten the scan period and to reduce the effect of statistical noise on quantitative outcomes using computer simulation and human PET studies with 18F-FE-PE2I.
