Seminars in Ultrasound, CT and MRI. https://doi.org/10.1053/j.sult.2019.07.002https://hdl.handle.net/1805/21133The increasing availability of hybrid PET/MRI systems has led to a breadth of new publications and opportunities for use of PET/MRI. While PET/CT has been a valuable tool for oncologic staging, including head and neck malignancy, there are several theoretical and practical advantages a PET/MRI system would have over PET/CT in head and neck imaging. This review article discusses the established role of PET/CT, early evidence for the role of PET/MRI, and protocol considerations for both PET/CT and PET/MRI as they apply to head and neck imaging.enPublisher Policysquamous cell carcinomaPET/CToncologic imagingArticle
