  1. FDG-PET/CT fluorodeoxyglucose positron emission tomography/computed tomography, FBG fasting blood glucose, SUVmax maximum standardised uptake value
  2. aResults of the second PET/CT scan, even though 3 follow-up scans could be performed
  3. bUptake sites: 1 = tracheal/bronchial cartilage; 2 = nasal cartilage; 3 = costicartilage; 4 = arytenoid cartilage; 5 = hyoid cartilage; 6 = cricoid cartilage; 7 = thyroid cartilage; 8 = auricular cartilage; 9 = lymph node; 10 = auricular cartilage; 11 = vocal cord; 12 = lung; 13 = eye muscle
  4. cIf the FDG uptakes were in different positions of the same cartilage, SUVmax should be representative of the highest one
