Study Summary
Healthy volunteers aged 21 to 50 are needed for a research study investigating whether pain will alter the binding properties of (\[11C\]diprenorphine), a molecule that can be used during brain imaging. Positron Emission Tomography (PET) and functional Magnetic Resonance (fMRI) imaging will be used in this study.
Primary Outcome
Simultaneously collect fMRI-PET data in humans to investigate the change between bold signal evoked by pressure pain and bold signal evoked by non-painful pressure. The PET analyses generates one value per 120 minutes. This value is compared to the other 120 minute scan PET value in order to reflect the change.
Interventions
- RADIATION PET imaging
