It is a medical concoction that is used to provide contrast in the X-rays, during an Upper G.I. exam. It is comprised of Barium Sulphate.

Both a barium swallow and a barium meal test involve you swallowing a liquid suspension of barium sulphate before a series of X-rays are taken of your upper digestive tract. In a barium swallow test, X-ray images are taken of your pharynx (throat) and your oesophagus (the passageway that connects your throat to your stomach; sometimes called your gullet).

In a barium meal test, X-ray images are taken of your stomach and the beginning of your duodenum (the beginning of your small intestine, the passageway that takes food away from your stomach). A barium meal test is often performed straight after a barium swallow test.

Barium is a naturally occurring element that appears white on X-ray. In these tests, the barium is given as a cup of flavoured drink - like a milkshake. When swallowed, barium coats the walls of the digestive tract, which allows the shape of your upper digestive tract to be outlined on an X-ray. Without the barium your upper digestive tract would be barely visible on X-ray.

This procedure is called Barium Meal and follow through-( Ba meal FT)

Yes.

In fact, barium is often put into the body before regular x-rays to outlinet the gut (in the case of barium meal, barium follow-through and barium swallow).
