Abstract: |
Accurate radiographic diagnosis of head and neck cancers is challenging due to the anatomic and functional complexity of the head and neck region. Defining locoregional and distant spread of tumors is critical to cancer staging, treatment planning, and prognostication. A multimodality approach is necessary, incorporating ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI), and combined positron emission tomography and CT (PET/CT) to assess the anatomic and functional status of disease. Modality selection and utilization is tailored depending on the organ of interest and whether imaging is acquired for diagnosis, staging, treatment planning, and/or surveillance. Recent advances in the application of anatomic, functional, and metabolic imaging to head and neck cancers have allowed for more accurate and earlier diagnoses, demonstrating great potential to improve patient outcomes by assessing tumor histology, aggressiveness, unknown primary tumor sites, and identifying tumor recurrence. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022. |
