MRI contrast agents

thumb|alt=The nucleus is depicted by two red circles with inscribed plus symbols and one purple circle with no inscription. Around the nucleus there is a black ring - a symbol of an electron shell. On it are two teal circles with inscribed minus symbols, depicting electrons.|Diagram of a Helium-3 atom Helium-3 (3He see also helion) is a light, stable isotope of helium with two protons and one neutron (in contrast to the more common isotope, helium-4, which has two protons and two neutrons.) Helium-3 and hydrogen-1 are the only stable nuclides with more protons than neutrons. It was discovered

Perflubron (INN/USAN, or perfluorooctyl bromide; brand name Imagent) is a contrast medium for magnetic resonance imaging, computer tomography and sonography. It was approved for this use in the United States by the Food and Drug Administration in 1993.

complex of gadolinium by DTPA and meglumine

Gadodiamide, sold under the brand name Omniscan, is a gadolinium-based MRI contrast agent (GBCA), used in magnetic resonance imaging (MRI) procedures to assist in the visualization of blood vessels.

type of contrast agent used for magnetic resonance imaging

Gadobutrol (INN; Gd-DO3A-butrol) is a gadolinium-based MRI contrast agent (GBCA). It received marketing approval in Canada and the United States. As of 2007, it was the only GBCA approved at 1.0 molar concentrations.

Mangafodipir (sold under the brand name Teslascan as mangafodipir trisodium) is a contrast agent delivered intravenously to enhance contrast in magnetic resonance imaging (MRI) of the liver, and has potential to serve as an adjunct for various chemotherapeutic agents and during coronary intervention. It has two parts, a paramagnetic manganese(II) ion and the fodipir (dipyridoxyl diphosphate, DPDP) chelating agent. When freed from the organic ligand, the manganese shortens the longitudinal relaxation time (T1) in an MRI scan. Normal liver tissue absorbs the manganese more than abnormal or cance

Gadoversetamide is a gadolinium-based MRI contrast agent, particularly for imaging of the brain, spine and liver. It is marketed under the trade name OptiMARK.

Gadopiclenol, sold under the brand name Elucirem or Vueway among others, is a contrast agent used with magnetic resonance imaging (MRI) to detect and visualize lesions with abnormal vascularity in the central nervous system and in the body. Gadopiclenol is a paramagnetic macrocyclic non-ionic complex of gadolinium.

Gadoteridol (INN) is a gadolinium-based MRI contrast agent, used particularly in the imaging of the central nervous system. It is sold under the brand name ProHance. Gadoteridol was first approved for use in the United States in 1992.
