Gadoxetate disodium is primarily used as a contrast agent in magnetic resonance imaging (MRI) to enhance the visualization of the liver. It is particularly effective in detecting and characterizing liver lesions, such as tumors, cysts, and metastases. The agent is taken up by hepatocytes (liver cells) and excreted into the bile, providing detailed images of the liver parenchyma and biliary system. This makes it invaluable for diagnosing liver conditions, planning surgical interventions, and monitoring treatment responses. Its ability to improve the contrast between normal and abnormal tissues aids radiologists in making more accurate and timely diagnoses.
