Only the RF diet led to decreased D2BP.
Participants completed PET imaging with the radiolabeled D2-like receptor subtype antagonist [Compared with baseline, the RF diet significantly decreased D2BP in bilateral striatal clusters spanning the left putamen and right caudate/putamen (The cluster where D2BP was decreased during the RF versus the baseline diet was localized to the white/gray matter boundary of striatal nuclei. To rule out potential localization errors due to image misalignment, individual subject alignment data were visually checked independently by 2 members of the study team, and the mean group D2BP by diet condition was verified to map well with the template anatomical image in Talairach space (
