Novel radiotracer(s) for Positron Emission Tomography (PET) imaging are described. Novel radiotracer(s) for Positron Emission Tomography (PET) imaging of neuorendocrine tumors are described. Specifically the present invention describes novel [18F]Fluoroethyltriazol-[Tyr3]Octreotate analogs; in particular those that target somatostatin receptors found on the cell surface of gastroenteropancreatic neuorendocrine tumors. The present invention also describes intermediate(s), precursor(s), pharmaceutical composition(s), methods of making, and methods of use of the novel radiotracer(s).
