Magnetic resonance imaging of the larynx.

Abstract

Magnetic resonance imaging (MRI) is now considered the imaging modality of choice for the evaluation of the larynx. The most common indication for MRI of the larynx is to aid in the staging of patients with possible or known laryngeal carcinoma. This article presents the normal MRI anatomy of the larynx in three orthogonal planes. Respiratory maneuvers were also performed during imaging sequences to demonstrate their physiological effects and to examine the feasibility of performing such maneuvers during an imaging sequence. Included in this article is a brief discussion of the use of MRI in the staging and treatment of laryngeal carcinoma.
