High-osmolar contrast media (HOCM) are the oldest agents. They are relatively inexpensive, but their utility is limited. They are monomers (single benzene ring) that ionize in solution with a valence of -1. Their cation is either sodium or meglumine. A major advance was the development of nonionic compounds.Intravenous administration of a gadolinium-based contrast agent (GBCA) is indicated in over one-third of MRI examinations to obtain the necessary information. While GBCA is well tolerated in most patients, it is associated with a small risk for nephrogenic systemic fibrosis (NSF) or acute adverse reaction.Contrast media is frequently used to enhance these differences. The intrinsic factors that contribute to contrast are 1 H proton density, the relaxation times of 1 H protons, and magnetic susceptibility . Because it is not possible to change tissue proton density, alteration of tissue relaxation times and susceptibility have been the major ...

You might need contrast when you are having an X-ray, CT, MRI, or ultrasound exam. It can be an iodine-based material, barium-s ulfate, gadolinium, or saline and air mixture that can be swallowed or injected intravenously. Contrast distinguishes, or “contrasts,” between organs, tissues, bones, or blood vessels during your imaging exam.
