PET/CT images from a 66-year-old male diagnosed with p16-negative oropharyngeal squamous cell carcinoma in the soft palate. Transverse 11C-4DST PET image (a) and fused PET/CT image (b) show an increased uptake in the primary tumor (SUVmax = 8.00, homogeneity = 0.295, entropy = 2.050, SRE = 0.965, LRE = 1.140, LGZE = 0.00514, and HGZE = 260.00). Transverse 18F-FDG PET image (c) and fused PET/CT image (d) also show an increased uptake in the primary tumor (SUVmax = 14.57, homogeneity = 0.194, entropy = 1.970, SRE = 0.986, LRE = 1.060, LGZE = 0.00168, and HGZE = 843.90)
