This article reviews the use of imaging modalities; both commonly used and recently introduced, to evaluate oral cancers and their lymph node metastases. Magnetic resonance images (MRI) and X-ray computed tomography (CT) images are used to determine the size, invasive area, and possible pathology of primary cancers. In addition, the two modalities are useful for staging and detecting clinically occult lymph node metastases at different levels of the neck. In particular, a follow-up MR examination method, dynamic MR sialography, for patients with xerostomia after radiation therapy is introduced, and the use of fusion images of the tumors and vessels using threedimensional fast asymmetric spin-echo (3D-FASE) and MR angiography is discussed. Furthermore, ultrasound imaging (US), in addition to its use for staging and detecting clinically occult lymph node metastases, plays an important role in confirming intraoperative surgical clearance of tongue carcinomas. In addition, the role of US-guided, fine-needle aspiration biology is also reviewed. Finally, the role and limitations of fusion images obtained from positron emission tomography (PET) and CT (PET-CT), which are currently used worldwide, are discussed.
