The oral cavity is anterioly located and unique in the variety of tissues contained in this area. Although oral cancer screening may be done on clinical examination, imaging plays a critical role in staging and determination of deep margins for either tumor resectability or radiation planning. This article discusses the relevant anatomy on magnetic resonance imaging (MRI), including the lips and gingiva, floor of mouth, and oral tongue. This is followed by a discussion of standard MRI techniques, American Joint Committee on Cancer (AJCC) classification, and relevant MRI findings with discussion and imaging examples of carcinoma in major sites, including floor of mouth, oral tongue, buccal mucosa, bony upper alveolus, hard palate, and retromolar trigone. A brief summary of newer imaging techniques for evaluation of oral cancer is also presented.
口腔位于身体前部，该区域所含组织种类独特。尽管口腔癌筛查可通过临床检查进行，但影像学在肿瘤分期以及确定肿瘤可切除性或放疗计划的深部边界方面起着关键作用。本文讨论了磁共振成像（MRI）的相关解剖结构，包括唇部和牙龈、口底及舌体。随后讨论了标准MRI技术、美国癌症联合委员会（AJCC）分类，以及主要部位（包括口底、舌体、颊黏膜、上颌骨牙槽突、硬腭和磨牙后三角区）癌的相关MRI表现，并伴有讨论及影像学实例。还简要介绍了用于评估口腔癌的更新的成像技术。
