Iodinated contrast
Iodinated contrast is a type of contrast agent used in medical imaging to enhance the visibility of internal structures in the body. It is commonly used in procedures such as CT scans, X-rays, and angiography.
Composition[edit | edit source]
Iodinated contrast agents are compounds that contain iodine, a chemical element that absorbs X-rays. They are usually based on a tri-iodinated benzene ring, with different side chains added to improve the safety and effectiveness of the agent.
Uses[edit | edit source]
Iodinated contrast is used in a variety of medical imaging procedures, including:
- CT scans: Iodinated contrast is often used to enhance the visibility of blood vessels and organs in the body.
- Angiography: This procedure uses iodinated contrast to visualize the blood vessels in the body.
- X-rays: Iodinated contrast can be used to enhance the visibility of certain structures in the body during an X-ray.
Risks[edit | edit source]
While iodinated contrast is generally safe, there are some risks associated with its use. These include:
- Allergic reaction: Some people may have an allergic reaction to the iodinated contrast, which can cause symptoms such as itching, hives, or difficulty breathing.
- Kidney damage: In rare cases, iodinated contrast can cause kidney damage, especially in people with pre-existing kidney disease.
- Hyperthyroidism: The iodine in the contrast agent can sometimes cause an overactive thyroid, or hyperthyroidism.
Alternatives[edit | edit source]
In cases where iodinated contrast cannot be used, other types of contrast agents may be used instead. These include:
- Gadolinium-based contrast agents: These are often used in MRI scans.
- Barium-based contrast agents: These are used in certain types of X-ray examinations.
