PET images from a 69-year-old female diagnosed with nasopharyngeal squamous cell carcinoma. The orange-contoured area represents the area with an SUVmax greater than 2.5. Pretreatment transverse [11C]4DST PET image (a) shows an increased uptake in the primary tumor. Pretreatment transverse [18F]FDG PET image (b) also shows an intense uptake in the primary tumor. Interim (after 44 Gy of radiation) transverse [11C]4DST PET image (c) shows decreased uptake in the primary region. Interim (after 40 Gy of radiation) transverse [18F]FDG PET image (d) shows decreased uptake in the primary region. She was classified as showing a non-complete response at 3 months after treatment
