Contrat study of GIT
1- barium sulphate :the best contrast study of GIT
a-produce excellent opacification
B-good coating of the mucosa
c-compelety inert 1- barium sulphate :the best contrast study of GIT a-produce excellent opacification B-good coating of the mucosa c-compelety inert 1- barium sulphate :the best contrast study of GIT a-produce excellent opacification B-good coating of the mucosa c-compelety inert
The only disadvantage is that it may become solid and impacted
Why is barium used with x-rays
Barium is a dry, white, metallic powder that
is mixed with water to make a thick
, milkshake-like drink. Barium is an
x-ray absorber and appears white on x-ray film.
barium
Barium is made from pure barium sulphate ,
the particle of barium small (0.1-3 micro mm)
Disadvantage of barium :
Subsequent abdominal CT and US are difficult

2- gastrografin
have several disadvantage
a-hypertonic
b-irritant
c-less radio -opauetypes of contrast study
1-barium swallow
2- barium meal
3 barium follow through
4-barium enema
barium swallow
barium swallow is a radiographic (x-ray) examination
of the upper gastrointestinal (GI) tract, specifically
the pharynx (back of mouth and throat) and the esophagus
(hollow tube of muscle extending from below the tongue to the stomach).
barium swallow is a radiographic (x-ray) examination of the upper gastrointestinal (GI) tract, specifically the pharynx (back of mouth and throat) and the esophagus (hollow tube of muscle extending from below the tongue to the stomach).
reasons for the procedures
A barium swallow may be performed to diagnose structural
or functional abnormalities of the pharynx and esophagus.
These abnormalities may include, but are not limited to, the following:
cancers of the head, neck, pharynx, and esophagus
tumor
hiatal hernia - upward movement of the stomach, either into or alongside the esophagus
structural problems, such as diverticula, strictures, or polyps (growths)
esophageal varices (enlarged veins) muscle disorders (pharyngeal or esophageal),
such as dysphagia (difficulty swallowing) or spasms (pharyngeal or esophageal)
achalasia - the lower esophageal sphincter muscle does not relax and allow food to pass into the stomach
gastroesophageal reflux disease (GERD) and ulcer

Contraindications for a barium swallow may include, but are not limited to, the following:
bowel perforation
bowel obstruction or severe constipation
pregnancy
