What diseases can be checked by barium gastrointestinal fluoroscopy

Acute and chronic gastritis, enteritis, gastric ulcer, and intestinal obstruction can be checked, and the following is the description of barium meal. Barium meal The barium meal used for gastrointestinal examination is medicinal barium sulfate, because it is insoluble in water and lipids, so it will not be absorbed by the mucous membrane of the gastrointestinal tract, so it is basically non-toxic to human beings. 　Barium meal imaging, or GI barium imaging, is an examination method that uses barium sulfate as a contrast agent to show the presence or absence of lesions in the GI tract under X-ray irradiation. 　During the X-ray examination, the natural level contrast of black and white is shown because of the different densities and thicknesses of various organs and tissues in the human body. However, in some parts of the human body, especially the abdomen, because the density of several internal organs and tissues is generally similar, it is necessary to introduce a harmless contrast agent (such as medical barium sulfate) to artificially increase the display contrast in order to achieve the desired examination effect. This examination method is clinically called X-ray contrast examination, and the more widely used X-ray contrast examination is gastrointestinal barium meal contrast and barium enema contrast. This test is safe, non-invasive and has no side effects, but some patients, such as patients with acute respiratory tract infections, patients with severe cardiac, hepatic and renal insufficiency, and patients with positive iodine test, are generally not suitable for this test. 　Barium swallow or barium enema can only see the outline of the digestive tract, and the barium-filled digestive tract contrast often hides tiny lesions, so it is often taken orally or injected into the intestinal tract, so that the gastrointestinal tract has both high-density barium and low-density gas shadow, forming gas-barium contrast contrast, and it is easy to obtain positive results. According to the needs of clinical diagnosis and treatment, gastrointestinal barium meal contrast can be divided into upper gastrointestinal barium meal, whole gastrointestinal barium meal, colon barium enema and small intestine barium enema examination.　In medicine, if barium chloride and other soluble barium salts are mistakenly used as barium sulfate, soluble sulfate salts such as copper sulfate are usually used for detoxification. Barium ions are heavy metal ions that are very harmful to the human body. Citation such as sulfate ions can make barium ions and sulfate ions combined reaction to produce barium sulfate, thus lifting the danger.
