ABSTRACT
The larynx is amongst the commonest primary sites for head and neck cancer, and imaging represents an important tool for accurate staging of laryngeal tumours as well as detecting residual or recurrent disease. Computed tomography (CT) is the most frequently used modality to evaluate the larynx. However, magnetic resonance imaging, ultrasound, and 18F-fluorodeoxyglucose positron-emission tomography-CT (FDG PET-CT) represent important problem solving tools, most notably in the assessment of cartilaginous involvement, nodal disease and follow-up of patients treated with chemoradiotherapy, respectively. Newer techniques, such as dual-energy CT and dynamic contrast-enhanced imaging, may provide further useful information. This chapter will review the radiological anatomy of the larynx and discuss the imaging modalities employed to evaluate patients with laryngeal cancers.
