Techniques in Laryngeal Imaging—The State of the Art and Beyond

To date, computed tomography (CT) and magnetic resonance imaging (MRI) serve as the main techniques for imaging the larynx, although the use of positron emission tomography (PET) is increasing. Laryngeal trauma and evaluation of laryngeal malignancy represent the two most common indications for radiographic evaluation of the larynx. It is evaluation of the latter, however, to which the current preponderance of research effort has been dedicated. While CT and MRI are the most commonly used diagnostic media in laryngeal diseases, new techniques such as virtual laryngoscopy are allowing for non-invasive evaluation of the airway in detail that rivals that provided by traditional endoscopy.
