From: Cross-validation study between the HRRT and the PET component of the SIGNA PET/MRI system with focus on neuroimaging

Regional time activity curves for each subject for two target regions (left caudate and left putamen 1) and the reference region ([11C]DTBZ: occipital cortex, [18F]FDG: pons, [11C]raclopride: cerebellum) for all subjects. Note that the offset in time activity curves between the PET/MR and HRRT is due to different acquisition start triggering mechanisms (HRRT: manual acquisition start; PET/MR: acquisition start based on counts). Solid lines represent the PET/MR data, dotted lines the HRRT data
