When the spleen is of normal size, it is difficult to obtain a complete image in one section. The splenic hilum is the starting point for the correct identification of the spleen. The splenic hilum is defined as the entry point of the splenic vessels.

In micronodular cirrhosis of the liver, there is a diffuse increase in echogenicity and deformation due to scarring of the portal and hepatic veins. This is often associated with portal hypertension, splenomegaly, ascites, and dilation and varicose transformation of the splenic vein. The portal vein may have a normal or reduced diameter intrahepatically, but may be enlarged in the extrahepatic region.
Currently, liver ultrasound is the most commonly used method in hepatology. Liver ultrasound allows obtaining a cross-sectional image of the liver in an arbitrary plane and determining the depth and extent of the pathological process.
It is advisable to fast for 8 hours before the test. If there is a risk of dehydration, you can give clean water. In an emergency, you can conduct the test without preparation.
