| Description | Gadopentetic acid, also known as magnevist or gadopentetate, belongs to the class of organic compounds known as pentacarboxylic acids and derivatives. These are carboxylic acids containing exactly five carboxyl groups. Gadopentetic acid is a drug which is used for use with magnetic resonance imaging (mri) in adults, and pediatric patients (2 years of age and older) to visualize lesions with abnormal vascularity in the brain (intracranial lesions), spine and associated tissues as well as lesions with abnormal vascularity in the head and neck. Also used to facilitate the visualization of lesions with abnormal vascularity in the body (excluding the heart). This water molecule is labile and exchanges rapidly with water molecules in the immediate vicinity of the gadolinium complex. Gadopentetic acid is a very strong basic compound (based on its pKa). Outside of the human body, Gadopentetic acid has been detected, but not quantified in, arabica coffee. This could make gadopentetic acid a potential biomarker for the consumption of these foods. It is often used when viewing intracranial lesions with abnormal vascularity or abnormalities in the blood–brain barrier. It is usually injected intravenously. The unique charge characteristic of this complex allows researchers to inversely measure spin-lattice relaxation times as they are related to the concentration of proteoglycan aggregates and charged glycosaminoglycan side chains in articular cartilage. Its paramagnetic property 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. This alters their MRI properties and enables contrast enhancement to be achieved. It was described in 1981 by Hanns-Joachim Weinmann and colleagues and introduced as the first MRI contrast agent in 1987 by the Schering AG. Magnevist is a clear, colorless to slightly yellow solution containing 0.5 Mmol gadopentetate dimeglumine/mL(equivalent to 469.01 Mg/mL of gadopentetate dimeglumine). |
