The development of imaging modalities according to computer technology has proven to be a great breakthrough in diagnostic imaging. In this article, the role of imaging modalities, especially computed tomography (CT) and magnetic resonance imaging (MRI), for imaging of the oral cavity, submandibular region and metastatic cervical lymph nodes is discussed. Oral mucosal masses include benign neoplasms, minor salivary gland tumors, and malignant tumors. Staging of squamous cell carcinomas must focus on deep invasion, spread to the mandible and lymph nodes. The main entities are discussed with regard to which study is indicated and whether imaging can suggest a specific diagnosis. The imaging approach to these lesions is also discussed.
