PET and MRI in Prognosis Prediction of NPC

Nasopharyngeal carcinoma (NPC) differs from other head and neck malignancies terms of its epidemiology, pathology, and treatment outcome. Integrated PET/MRI is a new imaging modality, which can simultaneously acquire PET and MRI images. Considering the lack of reports on the use of hybrid PET/MRI systems in prognosis prediction in NPC, the investigators conduct this prospective study to investigate the roles of integrated PET/MRI parameters for predicting treatment outcome and prognosis in patients with NPC.
