How Do Nonionic Iso-osmolality Contrast Media Work?

Nonionic/iso-osmolality contrast media are iodine-based contrast agents used for imaging of the head and body.

Nonionic/iso-osmolality, water-soluble iodinated contrast agents, when given intravenously, improve the visibility of the blood vessels through which they pass. As a result, a clear image of the internal organs is obtained until the agent gets diluted and eliminated.

Nonionic/iso-osmolality contrast media are indicated for assessing the heart function and identifying any abnormalities.
