upper-GI study

A radiologic study in which a radiocontrast (e.g., a thick, barium-based substance) is ingested by the patient and images obtained from the upper-GI tract—oesophagus, stomach, duodenum.

Barium contrast is a viscid radiodense material, the use of which interferes with endoscopy and CTs.

Single contrast
Used to identify gastric outlet obstruction, GORD/GERD, hiatal hernia, varices or cancer of oesophagus.
