Summary
44Sc is a promising candidate for PET imaging and can be produced at medical cyclotrons via the 44Ca(p,n)44Sc reaction using highly enriched 44Ca targets. This study focuses on optimizing the production and purification of 44Sc to improve chemical purity and apparent molar activity, enhancing its potential for both preclinical and clinical applications. New separation methods using DGA (TrisKem International) and DOODA (Eichrom Technologies) resins were evaluated for their ability to efficiently separate scandium from macro quantities of calcium using hydrochloric acid, nitric acid and ammonium acetate as eluents. Based on these results, DGA and DOODA resins show comparable performance and have shown promise towards improved reproducibility.
