A 65-year-old man (patient 3). All lesions were verified by biopsies as true positive. A Imaging 15 min p.i. showed focal ¹⁸F-FDOPA uptake corresponding to two cervical lymph nodes (SUV_max = 6) and three thoracic lymph nodes (SUV_max = 10). B ¹⁸F-FDOPA uptake was no longer evident 59 min p.i. in the two cervical lymph nodes, and uptake in the thoracic lymph nodes was reduced (SUV_max = 5)
