¹⁸F-GP1 PET/CT images of a 63-year-old man with right common femoral artery endarterectomy and right popliteal artery angioplasty. Anterior maximum intensity projection and transaxial images of ¹⁸F-GP1 PET/CT at 120 min after injection show a focal increased uptake in the right popliteal artery (a, b; arrows), which corresponds to the AAT lesion after angioplasty (c). Additional positive ¹⁸F-GP1 uptake is observed in the dissected right distal external iliac artery (d, e; dotted arrows) and right common femoral artery (a, f; arrow heads) where endarterectomy was performed due to occlusion 3 days before ¹⁸F-GP1 PET/CT (g, arrow head)
