The research project “New SST₂R-antagonists in the diagnosis of neuroendocrine tumors with PET/CT” coded Ε12452 with a 1-year duration (2020-2022) is coordinated by Dr. T. Maina-Nock. It concerns a research cooperation of the Molecular Radiopharmacy team with the Department of Chemistry, Johannes Gutenberg University of Mainz, Germany, and sponsored by the ICPO Academy. The project aims at the development of new radiopharmaceuticals targeting neuroendocrine tumors in human, based on SST₂R-antagonists.
