PET results. Displayed data are the respective measurements of the maximum standardized uptake value (SUVmax). 18F-FDG, 18F-fluorodeoxyglucose; Lesions+, detected lesions and total lesions; M1, hottest haematogenous metastases; N/A, data not available; N1, hottest lymph node metastases; SD, standard deviation and TBR, tumor-to-background ratio of the primary tumor (* SUVmax of the primary divided by SUVmean of the background).
