For typical cirrhosis, B ultrasound can be seen, but early cirrhosis can not be detected by B ultrasound, including CT, MRI, etc. For early cirrhosis, sometimes it is easy to miss diagnosis and can not be detected. The early diagnosis of cirrhosis can only be made through liver puncture and pathological examination. The common causes of cirrhosis are viral hepatitis, alcoholic liver disease, etc. For patients with liver cirrhosis, early diagnosis, early detection and early treatment are needed to avoid the rapid development of liver cirrhosis. If the liver cirrhosis reaches the decompensation stage, severe complications such as ascites, liver palms, spider nevus, esophageal and gastric varices will also occur.
