Ga-68 PSMA Ligand: A Radiopharmaceutical for Localization of Prostate Cancer

"For PET/CT PSMA ligand scan, the subject will have catheter(s) placed for intravenous administration of \[68Ga\]PSMA ligand . Subjects will receive a single intravenous bolus of 2-5 mCi \[68Ga\]PSMA ligand and received PET/CT scan 60 minutes later. The data acquisition begin with non-contrast CT at 120kVp, automated mAs, and a pitch of 1.5, followed by PET acquisition from the mid-thigh to skull-base, 3 minutes each bed. After image acquisition, the subject will be observed for half an hour, and will be discharged if no adverse event happens.~The estimated organ doses show that the kidneys and the urinary bladder wall were the organs with the highest dose. As presented, the effective doses for patients were 0.023 mSv/MBq ± 15% (maximum deviation), leading to an effective dose of 3.4 mSv for an injected activity of 150 MBq."
