A 65-year-old woman was diagnosed as invasive adenocarcinoma of right upper lung (black or white arrow). The right hilar (10R) and mediastinal (4R) lymph nodes (red arrows) were all high-risk regional lymph nodes with a diameter greater than 1.0 cm (1.1–2.6 cm) and no CHA. These lymph nodes showed high [18F]FDG (SUVmax=10.9–21.3) and [18F]FAPI (SUVmax =10.0-12.5) uptake. Surgical pathology subsequently confirmed these lymph nodes as metastatic
