Gastrografin is described as which of the following properties?

• A. Water soluble, hyperosmolar, iodinated
• B. Non-ionic and non-iodinated
• C. Solid at room temperature
• D. Not used in CT imaging

Answer: (A)

Gastrografin is defined by being water-soluble, hyperosmolar, and iodinated. It’s an ionic contrast agent (not non-ionic) that contains iodine to appear radiopaque on imaging, and it’s a liquid at room temperature, not a solid. Because it is water-soluble and hyperosmolar, it can distend the bowel for CT imaging and is chosen for GI evaluations where perforation is a concern; it is indeed used in CT studies. The other descriptions—being non-ionic, solid, or not used in CT imaging—do not fit Gastrografin.
