Ultrasound can reveal cirrhosis, but it cannot be used as a basis for confirming the diagnosis of cirrhosis. Ultrasound is not sensitive to early cirrhosis and does not easily detect early cirrhosis, and about 1/3 of patients with cirrhosis do not show significant abnormalities on ultrasound. Early cirrhosis is best diagnosed by enhanced CT of the liver, enhanced MRI, and gastroscopic findings of esophagogastric-fundus venous varices. ultrasound usually indicates cirrhosis by images suggesting an unsmooth liver surface, disproportionate liver lobes, and uneven liver echogenic parenchyma, as well as portal hypertension by images such as splenomegaly and portal vein dilatation. ultrasound can also detect ascites, which is difficult to detect, and also It is an important initial diagnostic screening for cirrhosis combined with primary liver cancer. Ultrasound can also clarify the degree of cirrhosis by measuring the elasticity of the liver. Ultrasound is widely used in clinical practice because it is easy to operate, non-invasive and low cost.
