The document discusses various radiology procedures including barium enema, barium swallow, and barium meal. A barium enema uses barium and x-rays to detect abnormalities in the large intestine. It can detect issues like abdominal pain, rectal bleeding, and weight loss. Risks include inflammation, obstruction, and tears. Barium swallow examines the esophagus and stomach for issues like dysphagia and GERD. It should not be used if perforation is suspected. A barium meal examines the esophagus, stomach, and small bowel with x-rays to detect any abnormalities.
