    Contrast CT of a patient with brain metastases from breast cancer, before (left) and after (right) injection of iodinated contrast.. Iodinated contrast is a form of water-soluble, intravenous radiocontrast agent containing iodine, which enhances the visibility of vascular structures and organs during radiographic procedures.

  3. Iohexol - Wikipedia

    en.wikipedia.org/wiki/Iohexol

    Iohexol, sold under the trade name Omnipaque among others, is a contrast agent used for X-ray imaging. [4] This includes when visualizing arteries, veins, ventricles of the brain, the urinary system, and joints, as well as during computed tomography (CT scan). [4] It is given by mouth, injection into a vein, or into a body cavity. [5]

  4. Contrast agent - Wikipedia

    en.wikipedia.org/wiki/Contrast_agent

    A contrast agent (or contrast medium) is a substance used to increase the contrast of structures or fluids within the body in medical imaging. [1] Contrast agents absorb or alter external electromagnetism or ultrasound , which is different from radiopharmaceuticals , which emit radiation themselves.

  5. Contrast CT - Wikipedia

    en.wikipedia.org/wiki/Contrast_CT

    Contrast CT, or contrast-enhanced computed tomography (CECT), is X-ray computed tomography (CT) using radiocontrast. Radiocontrasts for X-ray CT are generally iodine-based types . [ 1 ] This is useful to highlight structures such as blood vessels that otherwise would be difficult to delineate from their surroundings.

  6. Radiocontrast agent - Wikipedia

    en.wikipedia.org/wiki/Radiocontrast_agent

    Iodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.

    However, history of allergy to iodine is contraindicated for the use of iodinated contrast. [ 3 ] A CT scan is typically performed after radiographic contrast media (dye) has been placed with fluoroscopic guidance into a sac-like lining (the first- and hardest and outermost- layer of the spinal meninges, the spinal dura mater ) surrounding the ...

    Also, the iodinated contrast medium used in contrast CT and contrast radiography can cause allergic reactions, including severe ones. [5] The contrast dye may also be toxic to the kidneys. [7] Because a cannula is inserted, there is also a risk of a cannula site infection, that may cause fevers or redness of the cannula area. [7]
