(a-b) A 63-year-old male with floor of mouth SCC. a PET/CT showed intense 18F-FDG uptake in the primary tumor(pathological T stage III, high probability of LN metastasis). b A LN with the most intense uptake of 18F-FDG was observed in the left neck side with SUVmax 1.76(Low probability of LN metastasis); The prediction model indicated the probability of nodal metastasis, which was confirmed by neck dissection (I-V). (c-d) A 55-year-old male with palate SCC. c PET/CT showed intense 18F-FDG uptake in the primary tumor(pathological T stage II, low probability of LN metastasis). d A LN with the most intense uptake of 18F-FDG was observed in the left neck side with SUVmax 4.62 (high probability of LN metastasis); The prediction model suggested probability of nodal metastasis, which was confirmed by neck dissection (I-V)
