Gadoteridol is a contrast agent used in magnetic resonance imaging (MRI) procedures. However, like all pharmaceuticals, it may contain impurities which can impact its safety and efficacy. Gadoteridol impurities refer to any unwanted substances present in the drug, such as residual solvents or by-products of the manufacturing process. These impurities must be carefully monitored and controlled to ensure the drug is safe for use in patients.
