In the only patient with PCa (3.7 cm3) among the whole cohort, the authors reported lower SUVmax values for [68Ga]Ga-DOTA-FAPi-04 than they did for [18F]FDG PET/CT in the absence of other information (i.e., ISUP, therapies, disease stage and PSA levels). This evidence concerns the gene KLK3 and posterior cortical atrophy.
