Computed Tomography Technologist Practice Exam

Question: 1 / 615

Which of the following is an example of an ionic low osmolar contrast medium (LOCM)?

Omnipaque

Iohexol

Hexabrix

Hexabrix is an example of an ionic low osmolar contrast medium (LOCM). Ionic LOCMs are characterized by their higher osmolality compared to non-ionic LOCMs, which can be crucial in certain imaging scenarios. Hexabrix, in particular, contains the ionic component amidotrizoate, which is responsible for its ionic characteristics.

In contrast, Omnipaque, Iohexol, and Isovue are all examples of non-ionic low osmolar contrast media. Non-ionic contrast agents are generally associated with fewer side effects and lower osmolality, making them more favorable for patients, especially those with a higher risk of adverse reactions. This distinction is vital in the context of patient care and safety during imaging procedures. Understanding the differences between ionic and non-ionic LOCMs helps in selecting the appropriate contrast medium for various diagnostic needs.
