How to check fatty liver

summary

More than a month ago, I didn't want to eat, especially now, sometimes I will feel sick. In the morning, I still have no strength. It's fatty liver. Now it's much better. Here, I'd like to share my experience on how to check fatty liver with you.

How to check fatty liver

Examination 1: blood biochemical examination: serum enzyme, B globulin, ferritin, ApoA1 and bile acid were often increased, albumin, bilirubin and prothrombin time (PT) were generally unchanged. Clinicopathological studies have found that only 20% - 30% of fatty liver have one or more of the above serological abnormalities, and there is no specificity, so laboratory examination can not accurately reflect fatty liver and its etiology.

Examination 2: CT: diffuse fatty liver showed that the density of liver (CT value) was generally lower than that of spleen, kidney and intrahepatic blood vessels. After contrast enhancement, intrahepatic blood vessels showed very clearly, and there was no abnormality in the shape and direction. The CT value of liver / spleen is often fixed, so the ratio of CT value of liver / spleen can be used as a reference standard to measure the degree of fatty liver, or as a basis for follow-up efficacy. CT has advantages in the diagnosis of fatty liver, and its accuracy is better than that of B-ultrasound, but its disadvantages are expensive and radioactive. In addition, MRI and hepatic arteriography are mainly used for those who are difficult to diagnose by ultrasound and CT, especially when it is difficult to differentiate focal fatty liver from liver tumor.

Examination 3: imaging examination, mild or moderate liver enlargement. Recently, we tend to standardize these criteria and judge the degree of fatty liver by comprehensive score. B-ultrasound can detect fatty liver with more than 30% liver fat content and fatty liver with more than 50% liver fat content. The sensitivity of ultrasound diagnosis can reach 90%. It has also been reported that the sensitivity of ultrasound in the diagnosis of fatty liver is 100% in non fibrotic liver. B ultrasound has been used as the first choice for diagnosis of fatty liver and is widely used in epidemiological investigation of incidence rate of fatty liver in the population. Recently, the positive predictive value of B-ultrasound in the diagnosis of fatty liver was 67%.

matters needing attention

On this, I would like to remind you: intake of fat should be appropriate: vegetable oil does not contain cholesterol, is conducive to the treatment of fatty liver. It should be controlled at about 50g per day, and high cholesterol food, such as meat oil and animal meat, should be restricted.
