Which imaging modality is considered an advance imaging for evaluating dysphagia and regurgitation?

• A. Video fluoroscopic swallow study
• B. Laryngeal examination
• C. Esophagoscopy
• D. CT scan

Answer: (A)

Dysphagia evaluation hinges on seeing how the swallow happens in real time. The video fluoroscopic swallow study provides dynamic, real-time X-ray visualization of the entire swallow—from the mouth through the pharynx and into the upper esophagus—with contrast. This lets you watch how the bolus is moved, how the swallow is coordinated, and whether airway protection is adequate. It also reveals problems like penetration, aspiration, post-swallow residue, and regurgitation across different consistencies and volumes. Because you can observe the timing and mechanics of the oral, pharyngeal, and esophageal phases in one study, it’s the most informative imaging for assessing dysphagia and regurgitation. Laryngeal examination focuses on structure and function of the larynx and vocal folds rather than the act of swallowing itself. Esophagoscopy looks at the esophageal mucosa and lumen but does not capture the dynamic swallowing process. CT scanning provides static anatomical images and doesn’t show the real-time sequence of swallowing, making it less suitable for functional assessment of dysphagia.
