Figure 1: Coronal, sagittal, and axial sections of 18F-fluoro-deoxy-glucose-positron emission tomography/computed tomography (upper panel) and 18F-fluoro-misonidazole-positron emission tomography/computed tomography (lower panel) of a representative patient from the study cohort. Note the large 18F-fluoro-deoxy-glucose-avid primary tumor in the left base of the tongue with maximum standardized uptake value of 13.27. Corresponding 18F-fluoro-misonidazole-positron emission tomography/computed tomography of the same patient acquired 3-h after injection of the radiotracer showing focalization of 18F-fluoro-misonidazole (circled in the axial section) with tumor background ratio >1.5 in the center of the 18F-fluoro-deoxy-glucose-avid primary tumor indicating the presence of hypoxia
