Gastrointestinal barium meal radiography, that is, gastrointestinal barium meal radiography, refers to an examination method that uses barium sulfate as contrast agent to show whether there are lesions in the digestive tract under X-ray irradiation.

X-ray examination, due to the different density and thickness of human organs and tissues, presents a natural level contrast between black and white. However, in some parts of the human body, especially in the abdomen, because the density of several internal organs and tissues is similar, it is necessary to introduce a contrast agent (such as medical barium sulfate) that is harmless to the human body and artificially improve the display contrast to achieve the ideal inspection effect. This method of examination is called X-ray photography in clinic. Gastrointestinal barium meal radiography and barium enema radiography are commonly used methods in X-ray photography. This test is safe, non-invasive and has no side effects, but some patients, such as patients with acute respiratory infection, patients with severe heart, liver and renal insufficiency, and patients with positive iodine test, are generally not suitable for this test.

Barium swallowing or barium enema can only see the outline of digestive tract, and barium-filled gastrointestinal radiography often covers up tiny lesions. Therefore, taking foaming agent orally or injecting gas into the intestine often makes both high-density barium shadow and low-density gas shadow in the gastrointestinal tract, forming gas-barium contrast, which is easy to obtain positive results. According to the needs of clinical diagnosis and treatment, gastrointestinal barium meal radiography can be divided into upper digestive tract barium meal, whole digestive tract barium meal, colon barium enema and small intestine barium enema examination.
