Barium Sulfate (Diagnostic)
Category- Diagnostic aid, radiopaque, gastrointestinal disorders
DescriptionBarium sulfate is a radiopaque agent. Radiopaque agents are used to help
diagnose certain medical problems. Since radiopaque agents are opaque to (block)
x-rays, the areas of the body in which they are localized will appear white
on the x-ray film. This creates the needed distinction, or contrast, between
one organ and other tissues. The contrast will help the doctor see any special
conditions that may exist in that organ or part of the body.
Barium sulfate is taken by mouth or given rectally by enema. If taken
by mouth, it makes the esophagus, the stomach, and/or the small intestine
opaque to the x-rays so that they can be "photographed". If it
is given by enema, the colon and/or the small intestine can be seen and photographed
by x-rays.
The dose of barium sulfate will be different for different patients and
depends on the type of test. The strength of the suspension and tablet is
determined by how much barium they contain. Different tests will require a
different strength and amount of suspension (some may require the tablet form),
depending on the age of the patient, the contrast needed, and the x-ray equipment
used.
Barium sulfate is to be used only by or under the direct supervision of
a doctor.
