Magnetic resonance can show cirrhosis of the liver. Cirrhosis of the liver can be detected by magnetic resonance examination to understand the morphology, size and pathological changes of the liver. MRI images of patients with cirrhosis can show significant reduction in liver size and widening of liver fissures, and can also show enlarged spleen and elevated portal vein pressure, which are the MRI imaging manifestations of cirrhosis. Many patients can determine the presence of cirrhosis by liver MRI. If it has progressed to cirrhosis, active liver preservation and anti-fibrotic treatment is required. Cirrhosis is a more serious chronic liver disease that can be caused by a variety of etiologies, the most common of which is viral hepatitis, especially hepatitis B, which also requires the administration of antiviral therapy.
