Abstract
With advances in cross-sectional imaging techniques and endoscopy in recent years, barium studies have decreased in volume overall; however, fluoroscopic studies remain a relatively inexpensive, safe, and readily available means for evaluation of the pharynx and esophagus (Gelfand et al. 1987; DiSantis 2008). Despite the decline in overall numbers of fluoroscopic procedures performed, the numbers of esophagrams and swallowing studies have actually increased (DiSantis 2008). The esophagram can provide necessary information about the morphology and function of the pharynx and esophagus (Ott et al. 1989). In addition to detailed anatomic and mucosal detail, esophageal motility can be assessed and gastroesophageal reflux diagnosed (Pan et al. 2003). The modified barium swallow provides information about a patient’s swallowing function and dietary requirements, especially for stroke and head trauma patients (Jones 2008).
