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]

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.
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.
Allergic reactions are rare. [1] The use of barium during pregnancy is safe for the baby; however, X-rays may result in harm. [4] Barium sulfate suspension is typically made by mixing barium sulfate powder with water. [1] It is a non-iodinated contrast media. [5] Barium sulfate has been known since the Middle Ages. [6]
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]
There is also a risk associated with the contrast dye in patients who are allergic to compounds containing iodine, which can be very severe, even if the anaphylactoid reactions occur while you are in a hospital. [23] [24] Oversedation can result in dangerously low blood pressure, respiratory depression, nausea, and vomiting. [citation needed]
