[¹⁸F]FDG (A) and ¹⁸F-PSMA (B) PET as well as [¹⁸F]FDG (C,E) and [¹⁸F]PSMA-1007 (D,F) PET/CT fused images of the chest in patient #7. Metastatic axillary lymph nodes showed uptake of both tracers (red arrows at (A–D)). However, mediastinal lymph nodes presented accumulation of [¹⁸F]FDG only (black arrow at (A)). A large metastasis in the left lung (green arrows) also showed a higher accumulation of [¹⁸F]FDG (A,E) than [¹⁸F]PSMA-1007 (B,F) with the SUV_max of 12.0 vs. 3.1, TBR 20.0 vs. 4.4. Benign post-irradiation pulmonary lesions in the right lung showed diffuse uptake of [¹⁸F]PSMA-1007 only (blue arrow at (B,F)).
