Radiohybrid compounds
Radiohybrids are molecules that can be used for both imaging and therapy. They provide a dual mode function: a diagnostic isotope and a therapeutic isotope are both always present, but only one of them is radioactive during application. For diagnosis, Fluorine-18 is used, while the second site is silent. For therapy, a beta- or alpha-emitting radiometal is used, whereas the fluorine is now silent.
