Gadopentetate dimeglumine Injection is indicated 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. Gadopentetate dimeglumine Injection has been shown to facilitate visualization of intracranial lesions including but not limited to tumors.
Gadopentetate dimeglumine is indicated for use with MRI in adults and pediatric patients (2 years of age and older) to facilitate the visualization of lesions with abnormal vascularity in the head and neck.
Gadopentetate dimeglumine Injection is indicated for use in MRI in adults and pediatric patients (2 years of age and older) to facilitate the visualization of lesions with abnormal vascularity in the body (excluding the heart).
Gadopentetate dimeglumineInjection is the N-methylglucamine salt of the gadolinium complex of diethylenetriamine pentaacetic acid, and is an injectable contrast medium for magnetic resonance imaging (MRI). Gadopentetate dimeglumine Injection is provided as a sterile, clear, colorless to slightly yellow aqueous solution for intravenous injection.
Gadopentetate dimeglumine Injection is a 0.5- mol/L solution of 1-deoxy-1-(methylamino)-D-glucitol dihydrogen [N,N-bis[2-[bis(carboxymethyl)amino]ethyl]- glycinato (5-)]gadolinate(2-–) (2:1) with a molecular weight of 938, an empirical formula of C28H54GdN5O20, and has the following structural formula:

Each mL contains 469.01 mg gadopentetate dimeglumine, 0.99 mg meglumine, 0.40 mg diethylenetriamine pentaacetic acid and water for injection. Gadopentetate dimeglumine Injection contains no antimicrobial preservative.
