Diagnostic performance of 18F-FDG PET/MR in head and neck malignancies

Conclusion: Our study highlight the better diagnostic value of PET/MR staging in primary tumor than cervical node for head and neck malignancies with 94% of the primary tumor and 82% of the regional nodes well-classified in comparison to pathology. One explanation lies on the insufficiency of the attenuation correction, but the high quality of images combined to the multimodal approach of PET/MR strengthens the diagnostic confidence by better tumor delineation and cervical node characterization. Therefore this modality appeared beneficial and promising for clinical practice. Research Support: Pitié-Salpêtrière Hospital
