Quantitative Imaging of and -Labeled Tracers in a Single "Multiplexed" PET Imaging Session
Sarah J Zou, Irene Lim, Jackson W Foster +5
In this study, we explore the use of Co-55 as a radioisotope for multiplexed PET (mPET) by utilizing its emission of a prompt gamma-ray in cascade with a positron during decay. We…
