Keywords: PET/MR, Head & Neck/ENT, ENT, head and neck, PET/MRI, lymph nodesThe aim of our study was to analyze the imaging characteristics of lymph nodes on pre-operative PET-MRI to find the predictors of recurrence or progression.273 patients with ATD cancer who underwent PET-MRI were included. Lymph node PET/MR analysis has shown that the strongest predictors of the recurrence were lymph node enhancement and SUVmax for the controlateral nodes and enhancement, SUVmax node shape for the homolateral nodes. In conclusion, PET-MRI can be an interesting tool in the pre-therapeutic assessment of primary tumors of the ADT with lymph node extension, particularly in the identification of predictive characteristics of recurrence or progression.
