Wavy uneven edges of the liver, widened hepatic fissure, diffuse decrease in the density of the liver parenchyma, CT value of about 47 HU, and non-uniform intrahepatic density in the form of multiple small nodules may be the CT manifestations of cirrhosis and fatty liver. In cirrhosis, the liver is reduced in size with granular edges, which may be manifested as jagged change of liver edges, disproportion of liver lobes, widening of hepatic fissure, and uneven density of liver parenchyma on CT; at the same time, portal hypertension manifestations, such as ascites, splenomegaly, etc., may also be present. Normal CT of liver is about 50-70HU, if the density of liver parenchyma is reduced on CT performance, CT value is lower than spleen can be diagnosed as fatty liver, this is due to the accumulation of fat in the liver resulting in reduced density of the liver. When the above description of CT terminology appears in the examination, it is necessary to consult a doctor in time and improve the relevant examination to clarify the cause of the disease and carry out standardized treatment under the guidance of the doctor.
