Liver parenchymal echogenicity means that no abnormal echoes are detected by liver ultrasound and the liver parenchyma is normal. Ultrasound, which uses ultrasound echoes to image the liver, is commonly used to examine the parenchyma and is safe, simple and non-invasive, making it the preferred screening method for liver examinations. Under normal circumstances, the overall density of the liver is the same, the texture is uniform, the ultrasound echo is also uniform, so the ultrasound report card “liver parenchyma echo homogeneity” is suggestive of the liver is normal, and there is no detection of masses and other foreign objects. If the liver parenchyma echo is not homogeneous, it suggests that there may be liver diseases caused by liver parenchyma damage, common diseases include viral hepatitis, long-term alcohol abuse, fatty liver, etc., which need to further check the function of the liver as well as improve the liver CT to clarify the cause of the disease.
