Time-activity curves from a healthy volunteer after i.v. injection of [¹¹C]SCH23390 in the morning (left) and afternoon (right). The curves were derived from realigned dynamic PET images using manually and automatically generated ROIs, respectively. PUT = putamen, DLPFC = dorsolateral prefrontal cortex, CBL = cerebellum. SUV = standardized uptake value = (C_ROI/inj dose) × body weight
