Evaluation of the In Vivo PET Generator 140Nd/140Pr Using a HER2-Targeting Agent.
Theranostic strategies using targeted radiopharmaceuticals frequently use f-block therapeutic radionuclides, such as 225Ac, 177Lu, and 161Tb; however, there are limited PET imaging counterparts within this chemical space. The in vivo PET generator pair 140Nd (half-life, 3.4 d; electron capture)/140Pr (half-life, 3.4 mi...
