What this record can show
This locally preserved record separates the registered protocol from source-reported registry results. Neither is a treatment recommendation.
Registry facts
The investigators will image brain cannabinoid receptors using Positron Emission Tomography (PET) imaging and the radioligand \[11C\] OMAR, in healthy individuals and individuals diagnosed with opioid use disorder. Research participants may complete screening, MRI, PET scan and follow up visits.
