contrast agent
A contrast agent, or contrast medium, is a substance used in medical imaging to enhance the visibility of structures within the body. When injected or ingested, it improves the clarity of images obtained through X-rays, CT scans, or MRI scans. This helps doctors see organs, blood vessels, and tissues more clearly, making it easier to diagnose conditions or diseases. The contrast agent highlights specific areas, providing vital information that aids in patient care and treatment decisions. Overall, it plays a crucial role in ensuring accurate medical evaluations.

A contrast agent is a special substance used in medical imaging to enhance the visibility of internal structures in the body, making them easier to see on scans like X-rays, MRIs, or CT scans. These agents may contain iodine or barium and are usually introduced into the body through injection, ingestion, or enema. They work by absorbing or altering the way imaging scans capture the images, which helps doctors identify abnormalities, diagnose conditions, or assess the effectiveness of treatments. Using a contrast agent can provide crucial information for patient care.
