Abstract:Aim: The purpose of this study was to assess the impact of the collimator in viewing the dopamine
transporter, using 123I ioflupane single-photon emission computed tomography (DaT-SPECT) images
utilizing a Monte Carlo simulation.
Methods: For the purpose of this study, the Monte Carlo simulation of electrons and photons (MCEP)-
SPECT was used. A numerical phantom was created from a real basal ganglia phantom and installed within
the code. The specific binding ratios (SBRs) were 5.03 and 2.01 for the background… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
