• Indication: 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).
