(Redirected from Radiocontrast)

Radiocontrast agent is a type of medical imaging agent used to improve the visibility of internal structures in X-ray based imaging techniques such as computed tomography (CT) or radiography.

Overview[edit | edit source]

Radiocontrast agents are substances that are used in radiology to enhance the visibility of certain structures or fluids within the body. These agents work by altering the way that X-ray or other forms of radiation are absorbed by the body, making it easier for the radiologist to distinguish between different types of tissue.

Types of Radiocontrast Agents[edit | edit source]

There are two main types of radiocontrast agents: Iodinated contrast and Barium sulfate.

Iodinated Contrast[edit | edit source]

Iodinated contrast is a type of radiocontrast agent that contains iodine. Iodine is a heavy element that absorbs X-rays very well and is used in a form that is relatively safe to inject into the body. Iodinated contrast agents can be used in a variety of imaging studies, including CT scans, angiography, and venography.

Barium Sulfate[edit | edit source]

Barium sulfate is another type of radiocontrast agent. It is a heavy metal salt that is not absorbed by the body and is therefore used to outline the gastrointestinal tract in X-ray imaging.

Side Effects[edit | edit source]

While radiocontrast agents are generally safe, they can cause side effects in some people. These can range from mild reactions like nausea and vomiting, to more serious reactions like anaphylaxis. In rare cases, radiocontrast agents can also cause kidney damage, especially in patients with pre-existing kidney disease.
