It is a high-density gastrointestinal contrast agent that can be made into suspensions of different proportions and used alone, but is usually used together with low-density gases to achieve the purpose of dual contrast. Commonly used for gastrointestinal imaging, according to domestic user reports, the uneven thickness of barium sulfate is superior to the fine and uniform barium sulfate. Be cautious when using for certain intestinal diseases such as appendicitis, diverticulum, ulcerative colitis, parasitic infections, etc. that can cause intestinal fistula and perforation.
