Pramipexole MRI suggests that atypical hepatic nodules may be associated with viral hepatitis, alcoholic hepatitis, cirrhosis and other diseases. 1. Viral hepatitis: virus causes necrosis of hepatocytes, destruction of liver lobules to form pseudo lobules, fibrosis and hyperplasia, and finally formation of liver nodules. 2. Alcoholic hepatitis: it is common in liver inflammatory injury caused by long-term excessive alcohol consumption, which results in hepatocyte necrosis, fibroplasia, and nodularity in the liver. 3. Cirrhosis: mostly caused by viruses, long-term alcohol consumption, malnutrition and parasites, resulting in chronic inflammation of the liver, diffuse fibrosis, and the appearance of nodules. When atypical liver nodules appear, it is recommended to consult the attending doctor in time, follow the doctor’s instructions for further examination, clarify the cause with the doctor’s help, and carry out targeted treatment or therapy.
