Liver ultrasound hypoechoic and hypoechoic refers to a description of the degree of attenuation of sound waves returned by the density of different tissues in liver imaging. Liver ultrasound hypoechoic may be benign or malignant lesions of the liver, and liver ultrasound hypoechoic generally suggests intrahepatic calcification or intrahepatic bile duct stones. 1. Benign lesions with low echogenicity in the liver are more common, such as accumulation of intrahepatic fat, hepatic cysts, and hepatic hemangiomas with focal nodular hyperplasia, etc. Malignant lesions include the primary cause of liver cancer and the secondary cause of liver cancer, which is the accumulation of fat in the liver. Malignant lesions include primary hepatocellular carcinoma, metastatic hepatocellular carcinoma, and intrahepatic cholangiocellular carcinoma. If only simple hypoechogenicity is present, it is impossible to determine the nature of the lesion, and enhanced CT, magnetic resonance and other examinations are needed to make a definite diagnosis. 2. Due to the hard texture of the stone, it will indicate hyperechoic in the examination. Calcified spots are nodules formed by localized inflammation and necrotic tissues in the liver, which are less harmful to the human body, and most of these patients do not have obvious clinical symptoms, and regular liver function tests, as well as bile duct ultrasound CT examination can be carried out. If hyperechoic or hypoechoic lesions are found in the liver, the patient should consult the doctor in time, complete the relevant examinations, make a clear diagnosis, and then take the corresponding treatment plan.
