Figure 10. Upright LPO spot image from double-contrast esophagography shows mild ringlike constriction (large white arrows) in midesophagus in a patient with Barrett esophagus. Also note distinctive reticular pattern (black arrows) extending distally from the stricture, a classic radiographic sign of Barrett esophagus. This patient also has fixed transverse folds (small white arrows) just above the stricture due to longitudinal scarring in this region.
