The average values of right and left ROIs were used to increase the signal-to-noise ratio for the quantification. A ROI for cerebellum was drawn below the appearance of the petrosal bone in five slices corresponding to a thickness of 10 mm. ROIs were applied to the PET images using the co-registration parameters to extract regional time activity curves.

We used positron emission tomography and the dopamine D2-receptor radioligand 11Craclopride in healthy subjects to study the dopaminergic effects of an amphetamine injection after pretreatment with naltrexone or placebo. In a rat model, we used microdialysis to study the modulatory effects of naltrexone on dopamine levels after acute and chronic amphetamine exposure. In healthy humans, naltrexone attenuated the subjective effects of amphetamine, confirming our previous results.
