Neuroendocrine tumors encompass a wide range of tumors which originate from neural crest cells. These tumors were thought to be rare tumors, however, with the advent of advanced diagnostic techniques along with better understanding of the clinical presentation and histology of these tumors, the incidence of these tumors is exponentially rising. As the incidence and detection rate of NENs increased, the concept of 'heterogeneity' came into picture, which in turn led to dual-tracer imaging with addition of FDG PET/CT. Despite an imaging-based decision-making approach for NENs, there is still a significant subset of patients where the imaging-based biomarkers fall short in disease assessment, prognostication and improving outcomes. Alternate pathways as well as better peptide vectors for targeting the somatostatin receptor need to be studied. In this article, we address the existing as well as emerging trends in radiopharmaceuticals used for NENs, which are likely to impact not just the diagnostic algorithms in future, but also management strategies.
