In addition, the use of 18F-FDG PET/CT in infections and inflammations is well documented in literature: guidelines drawn up by the European Association of Nuclear Medicine (EANM) and the Society of Nuclear Medicine and Molecular Imaging (SNMMI) suggest the utilization of 18F-FDG PET/CT imaging in acute and chronic infection, since high levels of glucose transporters (GLUT) are expressed in the cells involved in infections and inflammations [62]. The gene discussed is SLC2A1; the disease is infection.
