Gadoteridol — Uses, Dosage, Side Effects & Safety

Drug class: Gadolinium-based Contrast Agent (GBCA)

Overview

Gadoteridol is a contrast agent used during magnetic resonance imaging (MRI) scans to help create clearer images of organs, blood vessels, and tissues. It is especially useful for detecting abnormalities in the brain, spine, and other parts of the body. Gadoteridol works by altering the way MRI machines interact with your body's tissues, making certain areas appear brighter or more detailed on the scan. This helps doctors diagnose medical conditions more accurately. Key points for patients: Gadoteridol is given by injection just before or during your MRI. It is generally well-tolerated, but you should inform your healthcare provider if you have kidney problems, allergies, or have had a reaction to contrast agents in the past.
