QUESTION
For bronchography, Dionosil is used at dose rate?
OPTIONS
(A) 0.5 to 1.0 ml per kg BW
(B) 2.0 to 3.0 ml per kg BW
(C) 3.0 to 4.0 ml per kg BW
(D) 4.0 to 5.0 ml per kg BW
ANSWER
(A) 0.5 to 1.0 ml per kg BW
EXPLANATION
Dionosil is propyliodone, an iodinated contrast medium historically used for bronchography because it coats and outlines the bronchial tree radiographically. In veterinary bronchography, the required volume is relatively small, and the accepted dose range is approximately 0.5–1.0 mL/kg body weight. Larger volumes such as 2–3, 3–4, or 4–5 mL/kg would introduce excessive contrast medium into the airways and are not the standard bronchographic dose. Therefore, option (A) 0.5 to 1.0 mL/kg BW is correct.
