Fatty liver CT

CT scan findings include:

• A decrease in mean hepatic attenuation values proportional to the degree of increase of the hepatic triglycerids.
• Intrahepatic vessels are more clearly distinguished as hyperattenuating structures from the surrounding liver parenchyma.
• In normal individuals the attenuation value of the liver is slightly higher than that of the spleen. In fatty liver infiltration the attenuation values of both organs tend to be equal or the ratios may be reversed.
• Does not cause any mass effect nor contour deformation of the organ.
• Intrahepatic vessels follow their normal course through the lesion without deformity.
