Fluorine-18 fluorodeoxyglucose PET/computed tomography (F-FDG PET/CT) plays an important role in the staging, treatment planning, treatment response assessment, detecting recurrent disease, and predicting prognosis in patients with oral cavity and oropharyngeal squamous cell carcinoma. PET/CT has advantage especially in the detection of nodal, distant metastatic disease and second primary malignancy. PET/MR provides superior soft tissue contrast while decreasing radiation exposure, which is advantageous in evaluation of the primary tumor.
氟-18 氟代脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（F-FDG PET/CT）在口腔和口咽鳞状细胞癌患者的分期、治疗计划、治疗反应评估、检测复发疾病和预测预后方面发挥着重要作用。PET/CT 尤其在检测淋巴结、远处转移疾病和第二原发恶性肿瘤方面具有优势。PET/MR 提供了更好的软组织对比度，同时减少了辐射暴露，这有利于评估原发性肿瘤。
