Larynx: anatomic imaging for diagnosis and management.

Imaging with CT, MRI, or fluorodeoxyglucose F 18-positron emission tomography is often an important complement to laryngoscopy for diagnosis and management of laryngeal pathology. At most centers, CT is the most popular modality for general laryngeal imaging given its widespread availability, ease of acquisition, and familiarity to clinicians, whereas MRI and positron emission tomography are used as problem-solving tools. Frequent indications for laryngeal imaging include cancer staging, suspected submucosal abnormalities, vocal cord paralysis, laryngeal trauma, and laryngotracheal stenosis. This article reviews the primary imaging modalities used for evaluation of, normal cross-sectional anatomy of, and radiologic features of common diseases of the larynx.
