Functional tumor volumes (FTVs)
Boxplot diagrams indicating functional tumor volumes (FTVs), A: total FTVs (primary tumors and metastasis), B: FTVs in primary tumors only, C: FTVs in metastasis only, D: Comparison of tumorous lesions (n), in which measured tumor volumes were larger in FDG (dark grey) vs. in FAPI-46 PET (light grey). FDG = fluorodeoxy-D-glucose, FAPI = fibroblast activation protein inhibitor
