Contrast Media in Medical Imaging

Contrast media, or contrast agents, are substances used in medical imaging to improve the visibility of specific areas within the body. They are often injected into veins, swallowed, or inserted into cavities to enhance images obtained from techniques like X-rays, CT scans, and MRIs. By highlighting organs, blood vessels, or tissues, contrast media help healthcare providers identify abnormalities such as tumors or blockages. The use of contrast agents allows for more accurate diagnoses and better overall evaluation of a patient’s health. Most contrast agents are safe, though some individuals may experience allergic reactions.
