Gadoteric acid

Gadoteric acid is a macrocycle-structured gadolinium-based MRI contrast agent. It is composed of the organic acid DOTA (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) used for its chelating properties, and gadolinium (Gd3+). As a paramagnetic molecule, gadoterate develops a magnetic moment when placed in a magnetic field. This magnetic moment enhances the relaxation rates of water protons in its vicinity, leading to an increase in signal intensity (brightness) of tissues. More specifically, it reduces the T1 relaxation time (and to some extent the T2 and T2* relaxation times) in NMR, which is the source of its clinical utility. Increased signal brightness allows it to be used in imaging of blood vessels and of inflamed or diseased tissue where the blood vessels become 'leaky'. Gadoteric acid, as the FDA approved product Dotarem, is indicated for intravenous use with magnetic resonance imaging (MRI) in brain (intracranial), spine and associated tissues in adult and pediatric patients (2 years of age and older) to detect and visualize areas with disruption of the blood brain barrier (BBB) and/or abnormal vascularity.
