Fig. 2: Regional differences in Mu-opioid receptor binding between individuals at high and low opioid misuse risk.

A Significant differences in baseline MOR BPND between groups was obtained in the right amygdala, with individuals in the high-risk for opioid misuse group (PMQ-H) exhibited the highest mu-opioid receptor MOR BPND. B Significant relationships between opioid misuse risk scores and baseline µ-opioid BP were also observed.
