The 7mmx8mm slightly strong echogenic area seen in the liver may be intrahepatic stones, hepatic nodules, tumors and so on. 1. Intrahepatic stones: Intrahepatic bile duct stones can be manifested as slightly strong echogenic nodules in color ultrasound, which need to be further diagnosed by CT or MRI. 2. Liver nodules: long-term hepatitis B and other chronic liver injury diseases lead to liver fibrosis or even cirrhosis, and nodules appear, usually with multiple hyperechoic nodules, and the surface of the liver is uneven. 3. Tumor: Intrahepatic hemangioma and hepatocellular carcinoma can be shown as slightly strong echoes in ultrasound, hepatic hemangioma usually shows colorful blood flow in the tumor in ultrasound, hepatocellular carcinoma needs to be confirmed with alpha-fetoprotein and biopsy. The presence of 7mmx8mm slightly strong echogenic area in the liver needs to improve the relevant examination, clear diagnosis and active treatment.
