Barite (Ba(SO4)) 13462-86-7

Barium sulfate, double contrast agent for X - ray. It is a high-density gastrointestinal contrast agent and can be made into suspension of different proportions for use alone, but usually used together with low-density gas to achieve the purpose of double contrast. Often used for digestive tract imaging, according to domestic users, uneven size barium sulfate is better than fine and uniform barium sulfate. Careful use of intestinal fistula formation and prone to perforation of some intestinal diseases, such as appendicitis, diverticulum, ulcerative enteritis, parasitic infection.
