Examination of fatty liver can be diagnosed through imaging examination, laboratory examination, pathologic examination and other methods, and also combined with clinical manifestations. 1. Imaging examination: commonly used methods include abdominal ultrasound or CT. Ultrasound in patients with fatty liver is characterized by diffuse punctate hypoechoicity in hepatic area, which is higher than the spleen and kidney; CT examination can find diffuse decrease in hepatic density. 2. Laboratory examination: mainly check the liver function related indexes, such as alanine aminotransferase, glutamine aminotransferase, bilirubin and so on, there will be a certain degree of elevation. If blood biochemical examination reveals that lipid-related indexes, such as triglyceride, total cholesterol, free fatty acid and so on, are obviously elevated, the possibility of fatty liver is higher. 3. Pathological examination: Pathological examination through liver puncture biopsy is the gold standard for the diagnosis of fatty liver, patients with fatty liver can see obvious fat droplets in liver cells. However, this examination is invasive and is generally not preferred. 4. Clinical manifestations: patients with fatty liver are usually accompanied by epigastric discomfort, vague pain in the liver area, fatigue, anorexia, loss of appetite and other symptoms. If fatty liver is suspected, it is recommended to consult a doctor in time, complete the examination, make a clear diagnosis, and actively accept the treatment to avoid delaying the condition.
