a. Female, 62 years old, comparison of Al18F-NOTA-FAPI-04 and 18F-FDG uptake values in PDAC. Compared with FDG, FAPI PET imaging showed the lesions in the head of the pancreas clearly with higher TBR. The image quality of 15-minute, 30-minute, and 1-hour imaging can satisfy the diagnostic requirements (SUVmax: 12.9, 12.7, 10.1), where no uptake of FDG showed(SUVmax: 1.8). b. c. The SUVmax, SUVmean, TBR1, TBR2, and TBR3 values of Al18F-NOTA-FAPI-04 PET / CT imaging were significantly higher than those of FDG
