Strong echo of liver

We all know that the human liver is particularly important to the human body, because every night the liver is silently performing the detoxification function for our body. If there is a problem with the liver, the detoxification function will be damaged and the toxins in the human body will accumulate more and more. However, there are still some people who do not take care of their bodies and cause some liver diseases. When checking, they will find that the liver echo is thick and strong. What's going on?

The significance of thickening and enhancement of echo in liver B-ultrasound examination: Under normal circumstances, the echo inside the liver is composed of tiny light spots of similar size, similar brightness and uniform distribution. The intrahepatic echo becomes thicker and stronger with the progression of chronic liver damage, and the echo contrast between the liver and kidneys increases.

In patients with obvious connective tissue hyperplasia, diffuse linear echoes can be seen in the liver parenchyma, and sometimes small nodular echoes can be seen. These changes can occur in both chronic hepatitis and cirrhosis. Generally speaking, it is difficult to make a qualitative diagnosis of chronic hepatitis by ultrasound because its pathological changes are diffuse and lack specific manifestations on the sonogram. However, in cirrhosis, the echogenicity of the liver parenchyma changes significantly, and ultrasound findings are of high value in its diagnosis.

The echo characteristics of liver parenchyma in cirrhosis are: thickening and enhancement of echoes, and plaque-like strong echo areas can be seen; scanning with appropriate gain conditions, many low-echo small nodules are seen embedded in the liver parenchyma, the former are caused by fibrosis, and the latter are regenerative nodules; as the lesion progresses, liver structure disorder and inhomogeneous changes in liver parenchyma appear, which need to be differentiated from the sonograms of diffuse liver cancer.

The inner diameter of the main trunk of the portal vein in a normal person is generally 0.6-1.0cm, and can reach a maximum of 1.5cm. In a normal person, the inner diameter of the portal vein expands when taking a deep breath, because the diaphragm compresses the liver during inhalation, obstructing the outflow of blood from the liver. However, the inner diameter of the portal vein shrinks accordingly during a deep exhalation. Currently, the standard for liver B-ultrasound examination to indicate portal hypertension is ≥1.3cm. In portal hypertension, the amplitude of changes in the inner diameter of the portal vein and its branches with breathing is weakened or disappears. Through the introduction of the above content in the article, I believe that everyone has a deeper understanding and knowledge of liver B-ultrasound examination.
