The Role of Positron Emission Tomography/Computed Tomography Imaging in Head and Neck Cancer after Radical Chemoradiotherapy: a Single Institution Experience

The NPV of PET/CT after chemoradiation is consistent with the literature and underlines the importance of PET/CT in restaging the primary site if salvage neck dissection is considered. The overall PPV of PET/CT remains low but is high for nodal SUVmax > 4. These data could be used to design risk-stratified follow-up schedules.
