Positron emission tomography (PET) and suitable radioligands have been used to determine D2 dopamine receptor occupancy in the basal ganglia of patients undergoing neuroleptic drug treatment. The dopamine hypothesis of antipsychotic drug action has been supported by consistent PET findings of a high D2 dopamine receptor occupancy in patients treated with conventional clinical doses of chemically distinct classes of antipsychotic drugs (Farde et al. 1988; Smith et al. 1988; Baron et al. 1989).
