Triggered by the early success of ‘theran(g)ostics’, above all, the application of imaging agents in tandem with particle-emitting nuclides for diagnosis and endoradiotherapy of somatostatin-receptor 2 (SSTR2) positive neuroendocrine tumors (NET) [42], it appeared logical and obvious to adapt the same scheme to radiolabeled RGD peptides. Here, SSTR2 is linked to neuroendocrine neoplasm.
