Özet

[68Ga]Ga-PSMA-11, a urea-based peptidomimetic, has been widely used in recent years for PET imaging of patients with prostate cancer. Since it has short half-life and should be in-house synthesized, synthesis conditions may affect quality and in vivo behavior of [68Ga]Ga-PSMA-11. Therefore in this study we aimed to develop an alternative, simple and validated HPLC method to test chemical and radiochemical purity of [68Ga]Ga-PSMA-11 for clinical routine.
