However, our data show a higher (but also moderate) specificity and a higher PPV for 18F-PSMA (52% and 61% based on a SUVmax of 4.75) in comparison with 68Ga-PSMA (33% and 43% based on a SUVmax of 6.2), when differentiating between low- and intermediate-risk PC vs. high-risk PC (subgroup: csPCb), with comparable sensitivity (90% vs. 89%) and accuracy (63% both). Here, FOLH1 is linked to pachyonychia congenita.
