Upper Gastrointestinal Series Test
An individual who is suspected of having gastritis may need to undergo an upper gastrointestinal series test to help determine the underlying cause of their symptoms. The upper gastrointestinal series test is a radiographic diagnostic test that uses x-rays and a liquid suspension fluid to evaluate the duodenum, stomach, and esophagus. The liquid suspension is consumed by the patient having the test and is either a water-soluble contrast or barium. Images of internal bones, organs, and other tissues are made into images with the use of electromagnetic energy beams during an x-ray scan. The beams are passed through the patient's body tissues to plates specialized to produce a negative image. An upper gastrointestinal series test often contains a fluoroscopy study. Fluoroscopy is a procedure where a continuous beam of x-rays are passed through the part of the body the physician is examining and projects to a TV-like monitor. This allows the physician to see an x-ray video of the body parts while they are in motion. This test helps eliminate other possible causes of a patient's symptoms.
