The median fat attenuation of 291dB/m is significantly elevated. However, the specific severity of the condition needs to be judged in combination with liver function tests and clinical symptoms. Fatty attenuation refers to the degree of attenuation of liver fat, reflecting the severity of fatty liver. The normal value of median fat attenuation is 210~235dB/m, and the patient’s value is higher than the normal value, which suggests fatty liver. If the patient only has a median fat attenuation of 291dB/m and no symptoms in other tests, it means that the patient’s symptoms are not serious and can be effectively relieved through a low-fat, low-cholesterol, low-carbohydrate diet and moderate physical exercise. However, if the patient has a median fat attenuation of 291dB/m, accompanied by liver function abnormalities, or the presence of hyperlipidemia, diabetes and other diseases, suggesting that the patient’s condition is more serious. Timely consultation is needed, and the use of reduced glutathione and other medications should be standardized in accordance with medical advice, and surgical treatment should be used if necessary. It is recommended that patients with abnormal values of fat attenuation should go to the hospital in time to avoid delaying their condition.
