I*-(ipsilateral), brain regions located at the side of clinical symptoms onset (PD group); C*-(contralateral), brain regions located opposite to the onset side of clinical symptoms (PD group); ADP, anterior dorsal putamen; AVP, anterior ventral putamen; PDP, posterior dorsal putamen; PVP, posterior ventral putamen. ^†P-value from the comparison of the SUVR of healthy controls, I*-PD and C*-PD groups.
