VSR-0104
QUESTION
The contrast material used for effective radiography of gastro-intestinal tract in animal is?
OPTIONS
(A) Barium sulphate/paste
(B) Iodine dye preparations
(C) Copper sulphate
(D) Magnesium sulphate
ANSWER
(A) Barium sulphate/paste
EXPLANATION
Barium sulfate is radiopaque and ordinarily remains within the gastrointestinal lumen, allowing the tract to be outlined on radiographs when perforation is not suspected. Iodinated agents may be used when barium is contraindicated, but copper and magnesium sulfates are not standard diagnostic GI contrast preparations.
