Abstract
Barium sulfate is commonly employed for radiographic visualization of the gastrointestinal (GI) tract. For the upper GI (UGI), the barium sulfate mixture is swallowed and traced radiographically as it passes through the oropharynx, hypopharynx, esophagus, and more distal GI tract. When there is a concern of perforation or obstruction, water soluble contrast should be used.
