What can a gastrointestinal imaging exam detect?

Gastrointestinal contrast radiography, also known as upper gastrointestinal series or barium enema, is an imaging examination method that uses X-rays and contrast agent (usually barium) to evaluate the digestive tract.

It can help doctors visualize and diagnose various diseases such as gastritis, gastric ulcers, duodenal ulcers, gastric cancer, esophageal strictures, and diverticular disease. It can assess gastrointestinal motility and determine whether there are conditions such as delayed gastric emptying or esophageal reflux. It can also help detect ingested foreign bodies or other abnormal substances within the gastrointestinal tract.

It is also useful in evaluating esophageal diseases such as reflux esophagitis. Contrast studies allow observation of the morphology and function of the esophageal mucosa, helping to identify abnormalities such as congestion and erosion. For diseases such as intestinal bleeding, ulcers, polyps, and tumors, gastrointestinal contrast studies can provide valuable diagnostic information.

Particularly for gastrointestinal tumors, contrast examination can determine their location and morphology, localize intra-abdominal masses, and assess the extent and severity of tumor infiltration. It should be noted that in special situations such as acute peritonitis, gastrointestinal perforation, or severe diarrhea, this examination should be avoided to prevent worsening of the condition.
