Upper gastrointestinal angiography

Upper gastrointestinal angiography is a common method for gastrointestinal diseases. It refers to the gastrointestinal angiography above the duodenum. The upper gastrointestinal angiography includes the oropharynx, esophagus, stomach, and duodenum. Contrast agents are often swallowed during imaging, which is what the patient calls "swallowing potion." At present, barium agents such as barium sulfate are most commonly used, and barium glue paste is prepared by adding gum arabic, sometimes with foaming agents for double contrast, which can more clearly show the small lesions in the digestive tract.
