Gadoterate meglumine

Description:

Gadoterate meglumine, with the CAS number 92943-93-6, is a paramagnetic contrast agent primarily used in magnetic resonance imaging (MRI) to enhance the visibility of internal structures. It is a gadolinium-based compound, where gadolinium is chelated with meglumine, a sugar alcohol derivative that enhances the solubility and stability of the gadolinium ion in aqueous solutions. This compound is characterized by its high relaxivity, which improves the contrast between different tissues in MRI scans. Gadoterate meglumine is typically administered intravenously and is known for its low toxicity profile, making it suitable for patients with varying health conditions. It is generally well-tolerated, although, like all gadolinium-based agents, it carries a risk of nephrogenic systemic fibrosis in patients with severe renal impairment. The compound is also subject to strict regulatory oversight to ensure safety and efficacy in clinical use. Overall, gadoterate meglumine plays a crucial role in diagnostic imaging, aiding in the detection and characterization of various medical conditions.
