Gadoteric acid (trade names Artirem, Dotarem or Dotagita) is a macrocycle-structured gadolinium-based MRI contrast agent.

Perflubron (INN/USAN, or perfluorooctyl bromide; brand name Imagent) is a contrast medium for magnetic resonance imaging, computer tomography and sonography.

Gadobutrol (INN) (Gd-DO3A-butrol) is a gadolinium-based MRI contrast agent (GBCA).

Gadoxetic acid is a gadolinium-based MRI contrast agent.

Gadoversetamide is a gadolinium-based MRI contrast agent, particularly for imaging of the brain, spine and liver.

Ammonium ferric citrate has the formula (NH4)5Fe(C6H4O7)2.

Gadodiamide is a gadolinium-based MRI contrast agent, used in MR imaging procedures to assist in the visualization of blood vessels.

Gadoteridol (INN) is a gadolinium-based MRI contrast agent, used particularly in the imaging of the central nervous system.

Gadofosveset (trade names Vasovist, Ablavar) is a gadolinium-based MRI contrast agent.

Gadopentetic acid is one of the trade names for a gadolinium-based MRI contrast agent, usually administered as a salt of a complex of gadolinium with DTPA (diethylenetriaminepentacetate) with the chemical formula A2[Gd(DTPA)(H2O)]; when cation A is the protonated form of the amino sugar meglumine the salt goes under the name "gadopentetate dimeglumine".

Gadobenic acid (INN, trade name MultiHance) is a complex of gadolinium with the ligand BOPTA.

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.
