Gadoteric acid is primarily used as a contrast agent in magnetic resonance imaging (MRI). It enhances the visibility of internal body structures, particularly in the brain, spine, and associated tissues. This compound is particularly effective in diagnosing abnormalities such as tumors, inflammation, or blood vessel diseases. It is administered intravenously and works by altering the magnetic properties of nearby water molecules, thereby improving the quality and detail of the MRI images. Its use is critical in providing clearer, more precise diagnostic information, aiding in the accurate detection and assessment of various medical conditions.
