a Brain, b metabolite-corrected plasma and c olfactory bulb time–activity curves of (S)-[18F]GE387 with and without pre-treatment with 1 mg/kg of (R)-PK11195 in healthy naïve rats. Blocking effects of (R)-PK11195 are not observed to a significant extent in the healthy brain time–activity curves while plasma exposure is increased, possibly due to peripheral displacement of the radioligand
