Figure 3. An 18-F fluorodeoxyglucose positron emission tomography (FDG-PET) scan image. (A) Coronal section of FDG-PET scan, revealing high uptake around the ascending aorta and arch grafts, indicating inflammation around the grafts (Gelweave Valsalva™ and Triplex™). (B) Transverse section of FDG-PET CT scan at the level of aortic root (prosthetic valve and Gelweave Valsalva™). High uptake was noted in the aortic root, but not in the descending aorta. (C) Transverse section of FDG-PET CT scan at the level of aortic arch (Triplex™). High uptake was noted around the arch graft (Triplex™).
