(
Society of Nuclear Medicine and Molecular Imaging) Research presented at the 2019 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) describes a new class of radiopharmaceuticals, named radiohybrids (rh), that offer a fresh perspective on cancer imaging and radioligand therapy (theranostics). In addition, the technology encompasses a highly innovative and efficient isotopic labelling method to facilitate broad application.
