SUVpeak and TBR of 18 lymph nodes (1 node per patient). (A) SUVpeak of lymph nodes. (B) TBRmuscle with major pectoral muscle. (C) Blood TBR (TBRblood) with aorta as reference. Statistical significance of difference was assessed by Mann–Whitney U test.

Patient 10, 72-y-old man with urothelial carcinoma of bladder being evaluated for restaging after chemotherapy, showing mismatch of tracer-avid lymph node in 18F-FDG PET/CT and non–tracer-avid lymph node in 68Ga-FAPI PET/CT. Histopathology result was benign. 18F-FDG PET/CT images (A and B) and 68Ga-FAPI PET/CT images (C and D), maximum-intensity projections (A and D), axial CT (B and C, top), PET (B and C, middle), and fused PET/CT (B and C, bottom) are shown.
