A 63-year-old man with right oropharyngeal squamous cell carcinoma (arrowhead) as well as enlarged lymph node (arrow) in level II on right side. a Pretreatment PET-CT. b The corresponding ADC map. c The corresponding BF map. d The corresponding BV map. The primary tumor showed BF value of 126.7 mL/min/100 mL, BV value of 12.3 mL/100 mL, and skewness of ADC of 0.71. The metastatic node showed BF value of 119.4 mL/min/100 mL, BV value of 11.1 mL/100 mL, and skewness of ADC of 0.69. e PET-CT at 12 weeks post-treatment demonstrates the persistence of mild 18F-FDG uptake in the metastatic lymph node site. However, clinical and imaging follow up did not disclose any recurrence of primary tumor and lymph node
