Iodinated Contrast Media in Interventional X-Ray
Iodinated contrast media are water-soluble substances containing iodine that are used during interventional X-ray procedures to enhance the visibility of blood vessels, organs, and body tissues. Because iodine has a high atomic number, it absorbs X-rays efficiently, making anatomical structures appear radiopaque (white) on fluoroscopic and radiographic images. These contrast agents are essential in diagnostic angiography and image-guided minimally invasive procedures.
