Multiple Indications Cancer

Typically, PET scans involve an IV injection of 18F-FDG that helps identify cancer. Patients are scanned 60 minutes after injecting 18F-FDG. This study aims to assess the feasibility of a different method of administration - oral ingestion (rather than IV) of 18F-FDG through delayed imaging to identify the optimal time for scanning after consuming the drug. The study will aim to recruit 15-24 individuals who will receive two PET scans - one using delayed oral 18F-FDG imaging and a second regular 18F-FDG. The analysis will focus on establishing a suitable protocol for this administration route while considering patient preference and image quality.
