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.
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.
Relatively common side effects include vomiting, diarrhea, and skin redness. [4] Other side effects include itchiness, kidney problems, low blood pressure, and allergic reactions. [1] It is not recommended in people who have an iodine allergy. [1] Diatrizoate is an iodinated ionic radiocontrast agent with high osmolality. [2]
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] Side effects include vomiting, skin flushing, headache, itchiness, kidney problems, and low blood pressure. [4]
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.
Iobitridol is an iodine-containing radiocontrast agent. [2] [5] The iodine atoms readily absorb X-rays, resulting in better contrast in radiography images. [9] The quality of images made with this drug is equally good as with other low– or medium–osmolarity iodinated contrast agents such as iopamidol or iohexol. [5]
Contrast CT of a patient with brain metastases from breast cancer, before (left) and after (right) injection of an iodine-containing contrast agent. Ioxaglic acid is an iodine-containing, water-soluble radiocontrast agent. The iodine atoms readily absorb X-rays, resulting in a higher contrast of X-ray
Side effects are uncommon. [3] They include vomiting, skin flushing, headache, itchiness, and low blood pressure. [2] Rare side effects include seizures and allergic reactions. [2] It should not be used by those who have an iodine allergy. [2] Iotroxic acid is an iodine containing contrast media of the diionic dimer type. [4]
