Figure 2. Case examples of increased 18F-sodium fluoride uptake in saphenous vein bypass grafts.
Green arrows indicate the areas of increased 18F-sodium fluoride (18F-NaF) uptake within saphenous bypass grafts (top row) and computed tomography angiography of the corresponding saphenous vein bypass grafts (bottom row). We observed increased 18F-NaF activity both in grafts with advanced atherosclerosis (Patient 2 and 3) and in the absence of such lesions (Patient 1).
