Esophageal stenosis: three-dimensional multidetector CT and virtual endoscopy

The improvement in spatial, temporal, and contrast resolutions with the newest multidetector computed tomographic (MDCT) scanners opens the opportunity to explore other applications of the virtual endoscopy technique besides the colon and stomach evaluation. As a non-invasive technique, virtual esophagoscopy represents an alternative to conventional endoscopy for the assessment of esophageal stenosis. The procedure and diagnostic performance are reviewed. Findings of this modality are illustrated.
