[Functional MR imaging of the liver]

Area of Science:

• Medical Imaging
• Hepatology
• Radiology

Context:

• Traditional liver biopsy is invasive and risky, especially for patients with compromised liver function or requiring frequent monitoring.
• Magnetic resonance imaging (MRI) has advanced significantly, becoming a key tool for evaluating liver conditions.

Purpose:

• To explore the principles and clinical utility of functional MRI in diagnosing and staging diffuse liver diseases.
• To highlight MRI's capability in assessing liver functional reserve and portal hypertension.

Summary:

• Functional MRI methods enable non-invasive diagnostics and staging of diffuse liver diseases, including non-alcoholic fatty liver disease, hepatitis, fibrosis, cirrhosis, hemochromatosis, and hemosiderosis.
• These MRI techniques can quantify the sequelae of liver disease, such as reduced liver function and portal hypertension.

Impact:

• Provides a safer, non-invasive diagnostic approach compared to liver biopsy.
• Enhances the clinical management of diffuse liver diseases through accurate staging and quantification of complications.
• Facilitates improved patient follow-up and monitoring in liver disease management.
