Diffuse Liver Diseases

Diffuse liver diseases such as fatty infiltration, iron deposition and cirrhosis produce changes in mor phology and signal characteristics which can be characterised by MRI. Although these do not represent malignant disease processes cirrhosis in particular is of importance since it is a common association with hepatocellular carcinoma. Cirrhosis does not significantly alter the T1 or T2 relaxation times of liver although it will produce the classic morphological changes of caudate and left hepatic lobe enlargement and distortion and compression of intrinsic hepatic vessels. Extrahepatic findings such as ascites, splenomegaly and enlargement of the hepatic portal vein and its tributaries may indicate portal hypertension and collateral varices are easily detected.
