Question 1

Barium sulfate is commonly used as a contrast agent in gastrointestinal imaging. Its suitability for this purpose is primarily due to its:

Accepted Answer

C. High atomic number and insolubility, making it opaque to X-rays and non-absorbable. — Barium sulfate is effective as a GI contrast agent because its high atomic number provides good X-ray attenuation (opacity), and its extreme insolubility prevents systemic absorption, thus minimizing toxicity and making it safe for oral or rectal administration. High solubility would lead to absorption and toxicity, it does not emit gamma radiation, and its primary role is not anti-inflammatory.

Answer

B. Ability to emit gamma radiation for detection.

Answer

D. Potent anti-inflammatory properties that reduce gut irritation.
