摘　　要：目的探讨超声影像引导衰减参数(ultrasound guided attenuation parameter,UGAP)定量检测肝脏脂肪变性的可行性。方法选取2024年2-6月期间于大连大学附属中山医院行肝脏超声检查的患者102例,同时行UGAP检查和收集血脂、腹部CT检查结果,比较分析UGAP检测所得的衰减参数(attenuation coefficient,AC)与甘油三酯(triglycerides,TG)、胆固醇(thermoelectric cell,TC)以及体重指数(body mass index,BMI)的相关性。结果有74例影像学确诊为脂肪肝,其中轻度30例,中度18例,重度26例,另有28例影像正常患者作为健康对照组,脂肪肝组与对照组的BMI、TG、TC水平及肝脏CT值、肝脾CT比值差异存在统计学意义,年龄差异无统计学意义。健康对照组与脂肪肝组的AC值差异有统计学意义,其中轻度、中度、中度脂肪肝的各亚组间AC值差异也具有统计学意义。结论UGAP在无创、定量评估肝脏脂肪变性中具有一定的临床应用价值。Objective To explore the feasibility of ultrasound guided attenuation parameter(UGAP)in the quantitative detection of hepatic steatosis.Methods A total of 102 patients who underwent liver ultrasound examination in Affiliated Zhongshan Hospital of Dalian University from February 2024 to June 2024 were selected.UGAP,blood lipids and abdominal computed tomography(CT)findings were collected.The correlation of attenuation coefficient(AC)obtained by UGAP with triglycerides(TG),total cholesterol(TC)and body mass index(BMI)was analyzed.Results A total of 74 patients diagnosed with fatty liver disease were included in the study,including 30 mild cases,18 moderate cases,and 26 severe cases,and 28 healthy subjects with normal imaging findings were selected as the control group.There were significant differences in the BMI,TG,TC,liver CT value,and liver CT/spleen CT ratio between the fatty liver group and the control group,but age was comparable.There was a significant difference in AC value between groups,so as that among the mild,moderate and severe subgroups.Conclusion UGAP has certain clinical application value in the non-invasive and quantitative evaluation of hepatic steatosis.
