The American Joint Committee on Cancer (AJCC) released the 8th edition of the AJCC cancer staging manual in 2017 that includes significant modifications from the 7th edition in the sections on oral cavity cancer (OCC) and oropharyngeal cancer (OPC). These highlights comprise the incorporation of the depth of invasion and exclusion of extrinsic tongue muscle involvement in the T staging of OCC, the separation of OPC staging based on the high-risk human papilloma virus status, and the inclusion of extranodal extension in N staging. The recent introduction of integrated positron emission tomography and magnetic resonance imaging (PET/MRI) with 2-[F]-fluoro-2-deoxy-D-glucose (F-FDG) has demonstrated the advantages of simultaneous PET and MR imaging with higher soft-tissue contrast, multiplanar image acquisition, and functional imaging capability. This pictorial essay discusses the role of F-FDG PET/MRI in the diagnosis of OCC and OPC based on the new cancer staging system.
美国癌症联合委员会（AJCC）于2017年发布了第8版AJCC癌症分期手册，该手册在口腔癌（OCC）和口咽癌（OPC）章节中对第7版进行了重大修改。这些要点包括在OCC的T分期中纳入浸润深度并排除舌外肌受累情况，根据高危人乳头瘤病毒状态对口咽癌分期进行区分，以及在N分期中纳入结外扩展情况。最近引入的采用2-[F]-氟-2-脱氧-D-葡萄糖（F-FDG）的正电子发射断层扫描与磁共振成像一体化技术（PET/MRI），已展现出同时进行PET和MR成像的优势，即具有更高的软组织对比度、多平面图像采集能力和功能成像能力。这篇图文并茂的文章基于新的癌症分期系统，探讨了F-FDG PET/MRI在OCC和OPC诊断中的作用。
