• Oral administration of contrast medium:

 

For abdominal studies, it is necessary to delineate 
the bowel from other structures such as lymph 
nodes, abdominal masses & abscesses. Various types 
of bowel opacifying agents can be used:

 

- Diluted barium suspension (1% – 2%) e.g., EZCAT

 

- Water soluble agent (2% – 4%) e.g., Gastrografin

 

- Water alone, as a negative contrast agent.

 

Timing of the oral contrast administration is impor-
tant to ensure its even distribution in the bowel.
