Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The Brain Ketone Body Challenge Imaging Study will measure how the brain uses different fuels. To do this, radioactive compounds will be used during Positron Emission Tomography (PET) imaging. These compounds, called \[11C\]Acetoacetate (AcAc) and \[18F\] Fludeoxyglucose (FDG), are similar to the sugars and fats the brain already uses for fuel. These compounds safely allow researchers to see how the brain uses sugars and fats during PET scans.
