Antagonist radiotracers have shown only a low sensitivity for detecting competition from high-efficacy agonists at opioid receptors (ORs) in vivo. We report that [11C]PEO binds with high affinity to μ and κ-opioid receptors, is a full agonist, and concentrates in brain regions of rats with a high density of the μ-OR after intravenous injection. Blocking studies with μ and κ-OR selective compounds demonstrated
