Mechanism of action CT scan of three brain metastases from breast cancer. Before (left image) and after (right image) injection of a iodinated contrast agent similar to<unk> .<unk>  is an iodine-containing radiocontrast agent. The iodine atoms readily absorb X-rays, resulting in better contrast in radiography images. 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. Pharmacokinetics After intravenous infusion,<unk>  is distributed in the circulatory system and the interstitium. The substance is only marginally bound to blood plasma proteins (to about 2%) and to membrane proteins because the hydrophilic side chains of the molecule efficiently mask the central iodinated benzene ring. It is not metabolized but eliminated in unchanged form via the kidneys by glomerular filtration without active secretion or reabsorption. The elimination half-life is 1.8 hours. In people with kidney failure, the substance is instead eliminated via the bile duct.
