Study Arms:
- Period 1 Visit 1 - Cold PET-CT Vehicle, Visit 2 -Warm PET-CT Vehicle (Type: ACTIVE_COMPARATOR): 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.
- Period 1 Visit 1 - Cold PET-CT Vehicle, Visit 2 -Warm PET-CT Glucagon (Type: EXPERIMENTAL): 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 Glucagon at a dose of 50ng/kg/min without a cooling vest.
- Period 1 Visit 1 - Cold PET-CT Vehicle, no visit 2 as BAT negative (Type: ACTIVE_COMPARATOR): 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.~No brown adipose tissue (BAT) identified on visit 1, therefore no visit 2.
