Gadoteric acid, sold under the brand name Dotarem among others, is a macrocycle-structured gadolinium-based MRI contrast agent (GBCA). It consists of the organic acid DOTA as a chelating agent , and gadolinium (Gd 3+ ), and is used in form of the meglumine salt (gadoterate meglumine).
The contrast-enhancing effect is a result of the neutral complex of gadolinium and dihydroxy-hydroxymethylpropyl- tetraazacyclododecane-triacetic acid (butrol), which works to decrease differences in longitudinal relaxation times (T1) and differences in spin-spin or transverse relaxation times (T2).

Macronutrients are defined as a class of chemical compounds which humans consume in relatively large quantities compared to vitamins and minerals which provide humans with energy. Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [2]
DOTA is derived from the macrocycle known as cyclen.The four secondary amine groups are modified by replacement of the N-H centers with N-CH 2 CO 2 H groups. The resulting aminopolycarboxylic acid, upon ionization of the carboxylic acid groups, is a high affinity chelating agent for di- and trivalent cations.
Gadoxetic acid is a gadolinium-based MRI contrast agent. [4] Its salt, gadoxetate disodium , is marketed as Primovist in Europe and Eovist in the United States by Bayer HealthCare Pharmaceuticals .
Gadopentetic acid, sold under the brand name Magnevist, is a gadolinium-based MRI contrast agent. [2]It is usually administered as a salt of a complex of gadolinium with DTPA (diethylenetriaminepentacetate) with the chemical formula A 2 [Gd(DTPA)(H 2 O)]; when cation A is the protonated form of the amino sugar meglumine the salt goes under the name "gadopentetate dimeglumine".
