Theranostic radiopharmaceuticals are molecules that can safely carry radioactive isotopes inside targeted human tissues and help physicians get accurate images of tumours, allowing them to more effectively and precisely eliminate cancer cells. This branch of pharmaceuticals has attracted enormous interest in the last decade and several radiopharmaceuticals have been developed based on radionuclides such as Gallium-68 (Ga-68). In recent years Ga-68 radiopharmaceuticals have been used increasingly in clinical applications for cancer diagnostics and using Ge-68/Ga-68 generators. However, despite its usefulness, there are supply challenges related to this important isotope.
