Objective:To study the clinical application value of abdominal ultrasound in screening for fatty liver in healthy examinees by the Health Management Center.Method:Eighty individuals who underwent health examinations in the B-ultrasound room of our Health Management Center were selected as the research subjects.All 80 individuals underwent fatty liver screening using abdominal ultrasound,and the results of puncture biopsy were used as the"gold standard"to observe the screening results.The diagnostic efficacy of abdominal ultrasound in fatty liver was analyzed.Result:19 cases of fatty liver were detected by puncture biopsy in 80 physical examination patients,18 cases were detected by abdominal ultrasound,and 1 case was missed.The diagnostic sensitivity,specificity,and accuracy reached 94.74%,98.36%,and 98.75%,respectively;Among patients with fatty liver detection,the detection rate of 68.42%in males was higher than 31.58%in females(P<0.05);The detection rate of 78.95%in the age group of 30-60 years old showed a higher level compared to 10.53%under 30 years old and 10.53%over 60 years old(P<0.05);The detection rate of individuals with a BMI value of 23-26 kg/m2 or above is higher than that of individuals with a BMI value of 19-22 kg/m2(P<0.05).Conclusion:The Health Management Center uses abdominal ultrasound to screen for fatty liver diseases in healthy individuals,with a high detection rate.However,there is still a risk of missed diagnosis.The ultrasound room can use abdominal ultrasound as the basis and combine liver function index testing to diagnose diseases,especially focusing on screening for males,the age group of 30-60 years old,and individuals with high BMI values,further improving the disease detection rate and accuracy.
