It is used (as its meglumine salt) in magnetic resonance imaging (MRI) in brain (intracranial), spine and associated tissues of patients ages 2 years and older, to detect and visualise areas with disruption of the blood brain barrier and/or abnormal vascularity of the central nervous system. It has a role as a MRI contrast agent. It is a conjugate acid of a gadoterate."}]
