Radiocontrast Agent
Radiocontrast agents are a type of medical contrast medium used to improve the visibility of internal bodily structures in X-ray based imaging techniques such as computed tomography (CT) and radiography (commonly known as X-ray imaging). Radiocontrast agents are typically iodine or barium compounds.
Despite being part of radiology, magnetic resonance imaging (MRI) functions through different principles and thus utilizes different contrast agents. These compounds work by altering the magnetic properties of nearby hydrogen nuclei.
