Definition

A radiotracer composed of C-SNAT4 radiolabeled with the radioisotope fluorine F 18, with potential tumor imaging activity upon positron emission topography (PET)/computed tomography (CT). Upon administration, the C-SNAT4 moiety of fluorine F 18 C-SNAT4 selectively targets and binds to a tumor-associated antigen (TAA) on the tumor cell. During PET/CT, TAA-expressing tumor cells can be visualized.
