Overview

There are MRI scan findings helps in diagnosing autoimmune hepatitis. However, an MRI scan may be helpful in the diagnosis of complications of autoimmune hepatitis which include fibrosis, hepatomegaly, splenomegaly.

Cirrhosis
- Fibrosis and irregular nodular liver is seen on MRI in cirrhosis.
- MRI differentiates regenerating or dysplastic nodules from hepatocellular carcinoma by accurately determining the nature of focal lesions.
- MRI is used as a follow-up study to determine whether lesions have changed in appearance and size.
- MRI may accurately diagnose cirrhosis and determines disease severity.
Heterogeneous hepatic echotexture which suggest active inflammation of the liver.
Hepatomegaly
Splenomegaly
