VSR-0133
QUESTION
Which of the following is not a low osmolar contrast media?
OPTIONS
(A) Iopamidol
(B) Iohexol
(C) Iopromide
(D) Iothalamate sodium
ANSWER
(D) Iothalamate sodium
EXPLANATION
Iothalamate sodium is an older ionic iodinated contrast agent with relatively high osmolality. Iopamidol, iohexol, and iopromide are nonionic low-osmolality agents, so only iothalamate sodium fails the low-osmolality criterion in these choices.
