Upper GI series (Barium X-ray)A chalky liquid called Barium is swallowed, and as it passes through the digestive system it makes it possible for the oesophagus, stomach, and the small intestine to show up in X-rays. This gives your radiologist and physician the opportunity to evaluate the shape and movements of your digestive organs. As the barium solution does not contain nutrients, it is not a good test of how fast things move through the stomach or intestine, but can give some information. |
