Single-Photon Emission Computed Tomography Tracers in the Diagnostics of Neuroendocrine Tumors

Different imaging strategies have been developed targeting the peculiar features of neuroendocrine tumors (NETs). Metabolic characteristics and receptor expression on the tumor surface have been studied, and expertise and knowledge are increasing as a result of the implementation of fusion imaging and the development of more detailed positron emission tomography tracers. Scintigraphic study of NETs is the most diffused and convenient technique for evaluating patients suspected to have NETs.
