Comparatore attivo: Period 1 Visit 1 - Cold PET-CT Vehicle, Visit 2 -Warm PET-CT Vehicle
Visit 1. Participants underwent F-fluorodeoxyglucose (18F-FDG) positron emission tomography, computerised tomography-(PET)CT, whilst wearing a cooling vest and receiving an infusion of gelofusine. Visit 2 Participants underwent F-fluorodeoxyglucose (18F-FDG) positron emission tomography, computerised tomography-(PET)CT, whilst receiving an infusion of gelofusine without a cooling vest. |
