Cyclotron-produced 68Ga from enriched 68Zn foils.

The growing need and limited availability of generator produced 68Ga (T1/2 = 68 min) for PET has provided the impetus for alternative, high output, 68Ga production routes such as charge particle activation of enriched 68Zn using PET cyclotrons. The work presents a rapid production method for clinically useful 68Ga for radiolabeling. The focus is also to expand the production capacity of cyclotron solid target-produced 68Ga over generator produced and liquid solutions targets by using enriched 68Zn-foils that minimizes target preparation.
