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.
Iopromide is an iodinated contrast medium for X-ray imaging.It is marketed under the name Ultravist which is produced by Bayer Healthcare. It is a low osmolar, non-ionic contrast agent for intravascular use; i.e., it is injected into blood vessels.
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.
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.
After injection into a vein, 14% of the circulating ioxaglic acid is bound to blood plasma proteins, which is unusually high for a water-soluble iodinated contrast agent. [5] The substance is distributed in the body with a half-life of 12 minutes (range 4 to 17 minutes) and eliminated in un metabolized (unchanged) form via the kidneys with a ...
Diatrizoate, also known as amidotrizoate, Gastrografin, is a contrast agent used during X-ray imaging. [1] This includes visualizing veins, the urinary system, spleen, and joints, as well as computer tomography (CT scan). [1]
Iobitridol is generally well tolerated. [5] The only side effect observed in more than 1% of patients is nausea.Rare side effects (in fewer than 1 per 10.000 people) include anaphylaxis (severe allergic reactions), circulatory collapse, kidney failure, thyroid-related effects, and skin reactions such as Stevens–Johnson syndrome.
An intravenous cannula is required for the administration of iodinated contrast. The typical dose is 30-40 g of iodine (corresponding to 20–30 cc of 370 mg/ml iodine solution). [10] However, for patients at high risk of contrast-induced nephropathy, it is possible to reduce the required amount of contrast using dual energy CT.
