Representative images of the mean [11C]DTBZ, [18F]FDG, and [11C]raclopride tracer distribution for each subject. Color scales of the images were adjusted based on SUV values for each tracer separately with a common maximum between scanners. PET/MR data were reconstructed with TOF with PSF and filter using 4 iterations and 28 subsets; HRRT data were reconstructed using 6 iterations and 16 subsets and post-processed with a 2.0 mm FHWM Gaussian filter (standard in-house reconstruction). Note: Subject 4 was injected with a lower amount of [18F]FDG activity for the HRRT scan compared to the other scans; hence, noise characteristics differ accordingly
