Which of the following UGI projections positions will best demonstrate barium in the body and pylorus of the stomach?
positioning UGI.
What is the best position to demonstrate duodenal loop?
Digestive System -- UGI.
What is the position of the stomach in a Hypersthenic patient?

An upper GI barium series is the definitive method of diagnosing hiatal hernias (see the image below). A single-contrast barium swallow performed with the patient in the prone position is more likely to demonstrate a sliding hiatal hernia than an upright double-contrast examination.
