68Ga is used for labeling both small compound and macromolecules, such as 68Ga-PSMA targeting the prostate-specific membrane antigen or 68Ga-labeled tracers targeting the somatostatin receptor expressed by neuroendocrine tumors, which are considered as key applications for combined PET/MR [9–11]. The gene discussed is FOLH1; the disease is neuroendocrine neoplasm.
