Cirrhosis and fatty liver can be seen by ultrasound, but still need to be combined with other tests to make a comprehensive judgment. When patients with cirrhosis undergo ultrasound, the surface of the liver may be uneven and the echoes of the liver parenchyma are unevenly enhanced. On the other hand, when patients with fatty liver are examined by ultrasound, it is usually seen that the anterior field echoes of the liver are enhanced, the far field echoes are attenuated and the intrahepatic ductal structures are not clearly displayed. Due to the low sensitivity of ultrasound in the diagnosis of mild fatty liver, and easily affected by other factors. If liver abnormalities are detected by ultrasound, further CT, MRI, liver puncture and portal vein manometry should be performed to diagnose the disease in combination with medical history and symptoms, so as to avoid misdiagnosis and delay in treatment. For some patients who have cirrhosis and fatty liver, they can visit the doctor regularly to monitor their condition through ultrasound in order to adjust the treatment plan. It is recommended to consult regular hospitals to ensure the accuracy of the test results. Those with clear liver disease need to strengthen life care, such as ensuring sufficient sleep time and paying attention to the rationality of diet.
