Fully automated preparation of 68Ga-PSMA-11 at curie level quantity using cyclotron-produced 68Ga for clinical applications.

68Ga-PSMA-11 is currently one of the most investigated PET agents for imaging both recurrent prostate cancer and relevant metastases; however, the production and distribution of 68Ga-PSMA-11 is limited to a supply of only a few daily doses when using a commercially available 68Ge/68Ga generator. 68Ge/68Ga generators deliver only a modest amount of activity, up to 1850 MBq (50 mCi), when new, but it decreases with time. Additionally, the production of 68Ga/68Ge generators has not been able to meet the increasing demand of 68Ga radiotracers. In response to the need for a more economically viable alternative, the focus of this study was to provide a simple and efficient method for producing 68Ga-PSMA-11, using cyclotron-produced 68Ga that is ready for routine clinical practice.
