General radiography

Upper gastrointestinal radiography, commonly known as barium meal, 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, including esophagography, esophagogastrography and enterography. The contrast examinations conducted by the radiology department of our hospital are all carried out by appointment system, and different examinations have corresponding inspection schedules.

Do not take iron, iodine, sodium, bismuth, silver and other drugs 2 days before the examination. It is not advisable to eat more fiber and indigestible food 1 day before filming. Before filming 1 night, eat a diet with less residue, such as soybean milk, noodles and porridge. Special attention should be paid to fasting on the morning of radiography, including boiling water and medicine. For patients who want to have a barium enema examination by colonography, they should take laxatives in strict accordance with the instructions the night before the examination, prepare their intestines, empty their stools on an empty stomach the next morning, and then do barium enema after making sure there is no feces in the excrement. Avoid wearing clothes with more metal patterns on the day of inspection. Before inspection, please remove jewelry, belts, coins, keys and other items that may produce artifacts. It is recommended that patients be accompanied by family members who know Mandarin. The good cooperation of patients is the key to the success of angiography. Enterography needs repeated examination, and patients must follow the arrangement of radiologists.
