Imaging of the larynx: current concepts

Area of Science:

• Radiology
• Oncology
• Otolaryngology

Background:

• Laryngeal imaging is not always necessary for laryngeal abnormalities.
• Imaging's primary value lies in assessing speech conservation therapy feasibility.
• Understanding laryngeal anatomy and surgical landmarks is critical for accurate interpretation.

Purpose of the Study:

• To evaluate the utility of imaging modalities in laryngeal cancer assessment.
• To determine the optimal imaging approach for surgical planning and speech conservation.
• To highlight the importance of radiologist expertise in interpreting laryngeal imaging.

Main Methods:

• Comparison of Computed Tomography (CT) and Magnetic Resonance (MR) imaging for laryngeal evaluation.
• Consideration of patient cooperation and institutional equipment (high-field vs. low/middle-field MR).
• Focus on identifying key anatomical landmarks: ventricle, anterior commissure, and cricoid cartilage.

Main Results:

• MR imaging offers superior tissue differentiation for cooperative patients.
• CT provides a more consistent examination for uncooperative patients or those with secretions.
• Both modalities can yield excellent laryngeal imaging when interpreted by knowledgeable radiologists.

Conclusions:

• The choice between CT and MR depends on patient factors and available resources.
• Radiologist's understanding of laryngeal anatomy is paramount for effective imaging.
• Accurate laryngeal imaging aids in surgical decision-making and treatment planning for laryngeal pathologies.
