Fig. 2

Representative images of [18F]FDG PET-MR (sagittal slices of 2D TOF FLASH MR angiography sequences through the descending thoracic and abdominal aorta and the heart) showing a normal physiological [18F]FDG uptake in the heart and the paravertebral brown adipose tissue, and an increased [18F]FDG uptake in the descending thoracic aorta in the second-generation BALB/c IL1rn−/− mouse. A First-generation BALB/c IL1rn−/− mouse. B Second-generation BALB/c IL1rn−/− mouse. C Wild-type mouse. D Volumes of interest manually drawn (yellow: descending thoracic aorta; green: abdominal aorta). E Volumes of interest manually drawn after dilation by the neighbourhood method (yellow: descending thoracic aorta; green: abdominal aorta; pink: ascending thoracic aorta)
