Mangafodipir trisodium is primarily used as a contrast agent in magnetic resonance imaging (MRI) to enhance the visualization of liver lesions. It helps in distinguishing between healthy and diseased tissues, particularly in detecting and characterizing liver tumors. Additionally, it has been explored for its potential antioxidant properties, offering protective effects against oxidative stress in certain medical conditions. Its application in diagnostic imaging aids in improving the accuracy of liver disease diagnosis and treatment planning.
