Furthermore, 18F-FDG PET is an interesting tool for the evaluation of infections/inflammations as well, due to the ability of cells involved in infections/inflammations to express high levels of glucose transporters (GLUT), especially neutrophils and monocyties/macrophages (in particular, these cells may present a high expression of GLUT1 and GLUT3) [105]. The gene discussed is SLC2A3; the disease is infection.
