Pharmacokinetic modeling of [68Ga]PSMA-11 in primary prostate cancer patients Open
15 patients underwent a 60-minute dynamic [68Ga]PSMA-11 PET scan (patient 101P had its scan interrupted at 40 min) in list-mode with the field of view over the pelvic area. PET data were reconstructed with a 3D-Ordered-Subsets E…
