Used as a contrast agent in magnetic resonance imaging (MRI) to enhance the clarity of internal body structures. It improves the visualization of abnormalities such as tumors, inflammation, and blood vessel disorders in the brain, spine, and other organs. Gadodiamide works by altering the magnetic properties of nearby water molecules, resulting in brighter images on MRI scans. It is administered intravenously and is particularly useful in detecting lesions with disrupted blood-brain barriers. Due to its stability and excretion through the kidneys, it is suitable for patients with normal renal function.
