From: Comparison of PSMA-TO-1 and PSMA-617 labeled with gallium-68, lutetium-177 and actinium-225
Patient #01 PSMA PET images. A 68Ga-PSMA-11 PET MIP at + 60 min. B 68Ga-PSMA-TO-1 PET MIP at + 60 min. C 68Ga-PSMA-TO-1 PET MIP at + 120 min. Blood pool activity was higher with 68Ga-PSMA-TO-1 in comparison with 68Ga-PSMA-11 (red arrows). Tumor uptake in liver metastases was slightly higher with 68Ga-PSMA-TO-1 in comparison with 68Ga-PSMA-11 and increased at + 120 min (yellow arrows, SUVmean 6.0 to 8.0, + 33%). SUVmean values are available in Table 3
