Specific radiotracers such as 11C‐ and 18F‐choline, 11C‐methionine, 18F‐ DOPA, 68Ga‐DOTA‐somatostatin analogs, 68Ga‐ligand‐prostate specific membrane antigen (PSMA), 18F‐PSMA, and 68Ga‐fibroblast activation protein inhibitor (FAPI), are being clinically tested for the use of differentiating non‐neoplastic etiologies such as infection, noninfectious inflammation, and tissues with normally increased physiological uptake (e.g., the central nervous system).9 The gene discussed is FOLH1; the disease is infection.
