PSMA-PET images. (A) Representative examples illustrate the variability in the total tumor volume (TTV) among patients stratified by the number of metastatic lesions. (B) Case examples demonstrate TTV segmentation across a range of TTV values. Notably, as the tumor volume increased, a visible decrease in radiopharmaceutical uptake by normal organs is observed, particularly in the salivary glands, kidneys, and liver (denoted by brackets), a phenomenon known as the “sink effect.” SUV = standardized uptake value.

Two cases of pathologically confirmed intrahepatic cholangiocarcinomas in 68-year-old male patients. In both cases (A-H, case 1; I-P, case 2), CT scans (B, F, case 1; J, N, case 2) revealed intrahepatic bile duct dilation and suspected nodular lesions. While F-18 FDG PET/CT (A, C, D, case 1; I, K, L, case 2) failed to demonstrate abnormal tracer uptake (SUVmax 3.5, TBR 1.3 in Case 1; SUVmax 2.6, TBR 1.2 in Case 2), F-18 FAPI-04 PET/CT (E, G, H, case 1; M, O, P, case 2 ) showed positive uptake in the nodular lesions (SUVmax 9.7, TBR 3.5 in Case 1; SUVmax 9.6, TBR 3.3 in Case 2).
