WebIodine-based contrast media are usually classified as ionic or nonionic. Both types are used most commonly in radiology due to their relatively harmless interaction with the body and its solubility. Contrast media are primarily used to visualize vessels and changes in tissues on radiography and CT (computerized tomography). WebCurrently, four classes of contrast material are commercially available: ionic monomers, nonionic monomers, ionic dimers, and nonionic dimers. Contrast materials are administered mostly in volumes of 50–150 mL; the compounds are rapidly distributed in the body and are recovered mainly unmetabolized in urine within 24 hours.

High osmolality ionic compounds. 1800–2100 mOsm/kg water. Low osmolality ionic compounds. 600–850 mOsm/kg water. Nonionic compounds. 300–484 mOsm/kg water. WebIonic and nonionic contrast media may be monomeric or dimeric. Typically, 3 iodine atoms are delivered with each benzene ring of a contrast medium. If a contrast molecule contains only 1 benzene ring, it is called a monomer. To deliver more iodine with each molecule of contrast, 2 benzene rings may be combined to produce a dimer.

WebThe ionic radius of Gd +3 (108 pm) is very close to that of Ca +2 (114 pm). Free gadolinium is therefore a competitive inhibitor of physiologic processes that depend on Ca +2 influx, including voltage-gated calcium channels and the activity of some enzymes. All Gd-based MR contrast agents therefore use some sort of ligand to chelate (contain) the free ion … Web17 mrt. 2024 · Contrast media, also known as medical contrast mediums or contrast agents, are chemical compounds used to increase the contrast of structures or fluids within the …

WebIntroduction Iodinated contrast media are commonly used in medical imaging and can cause hypersensitivity reactions, including rare but severe life-threatening reactions. Although several prophylactic approaches have been proposed for severe reactions, their effects remain unclear. WebThis isosmotic contrast medium prevents bradycardia and hypotension during coronary arteriography, however, the lower iodine content leads to poorer contrast compared with conventional contrast media.
