  1. Injection data of FAPI-46/FDG and count of malignant findings. FTV measurement was performed by using a fixed threshold of CR 4.0 or in case of dual-tracer PET/CT a CR-adapted threshold as described before. Here, we show an overview of all lesions with a CR > 4.0 that are thus measurable for FTV. SD = standard deviation, CR = count rate, FDG = fluorodeoxy-D-glucose, FAPI = fibroblast activation protein inhibitor
