Barium sulfate suspension, often simply called barium, is a contrast agent used during X-rays. [1] Specifically it is used to improve visualization of the gastrointestinal tract (esophagus, stomach, intestines) on plain X-ray or computed tomography. [2] It is taken by mouth or used rectally. [3]
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.
It was used from 1908 in pre-operative skin preparation by Italian surgeon Antonio Grossich. [1] [2] In the United Kingdom, the development of an iodine solution for skin sterilisation was pioneered by Lionel Stretton. The British Medical Journal published the detail of his work at Kidderminster Infirmary in 1909. [3]
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.

Organic compounds containing iodine are also useful iodinated contrast agents in X-ray imaging. [4] Common side effects when applied to the skin include irritation and discoloration. [2] Supplementation during pregnancy is recommended in regions where deficiency is common, otherwise it is not recommended. [1] Iodine is an essential trace ...
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.
Iohexol, sold under the trade name Iodaque 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]
