When one or several PSMA-positive areas were detected by 89Zr-PSMA-DFO PET, the SUVmax within the corresponding area of the 18F-JK-PSMA-7 or the 68Ga-PSMA-11 PET scan was measured. The SUVmax of 89Zr-PSMA-DFO PET-2 (first measurement) was significantly higher than the SUVmax of the PET-1 scan with 68Ga-PSMA-11 or 18F-JK-PSMA-7 in the corresponding areas (P = 0.0001, paired t test).
