What does gastrointestinal tract imaging examine?

The digestive tract includes the esophagus, stomach, small intestine and large intestine, all of which are made up of soft tissue and lack natural contrast, so ordinary X-ray examinations are not effective. Contrast examination can show the morphology and functional changes of gastrointestinal lesions, and can also reflect the scope and nature of certain lesions outside the gastrointestinal tract. It is widely used in clinical practice.

It is often used to diagnose various digestive tract diseases, such as congenital malformations, inflammation, tumors, etc. Gastrointestinal radiography is divided into three types: ordinary barium sulfate radiography, double air barium radiography and air barium radiography. In clinical practice, barium meal radiography of the esophagus, stomach, small intestine, colon and rectum is called whole gastrointestinal tract radiography.

Things to note during the examination: Ⅰ. Stop taking drugs that are not X-ray-painted or affect gastrointestinal function 3 days before the examination. Such as bismuth subcarbonate and calcium gluconate. Ⅱ Eat less indigestible food and fast after dinner one day before the examination. Ⅲ Patients with gastric retention should undergo gastric lavage the night before examination. The purpose is to remove gastric contents and facilitate barium meal examination. Ⅳ Perform a full digestive tract barium meal examination. Take 100 grams of barium sulfate powder mixed with warm water before the examination.
