Gadoteridol is primarily used as a contrast agent in magnetic resonance imaging (MRI) to enhance the visibility of internal structures. It is particularly effective in imaging the brain, spine, and associated tissues, helping to detect abnormalities such as tumors, inflammation, or vascular issues. The agent improves the contrast between normal and pathological tissues, allowing for more accurate diagnosis and assessment of conditions. It is administered intravenously and is known for its stability and safety profile, making it a reliable choice in clinical settings.
