Proton dose and FDG PET response in esophagus cancer patients. The proton irradiation isodose distribution delivered to this esophagus cancer patient is shown overlain the treatment planning CT in coronal view in the left panel. The corresponding re-staging [18F]-FDG PET, obtained 6 weeks after completing radiation therapy, is shown overlain the CT in the center panel. There is enhanced FDG activity in the irradiated pulmonary regions. The FDG uptake in lung tissue, normalized to unirradiated lung, vs. the radiation dose (in CGE) is shown in the right panel.
