研究目的:

1.建立学龄儿童UDFF的正常参考值范围; 2.采用病例对照研究对正常值进行验证,并探讨非酒精性脂肪肝病儿童UDFF的截断值,并根据SWE测值进一步评估儿童NAFLD的纤维化程度。  

Objectives of Study:

1. To establish a normal reference range for UDFF in school-age children; 2. A case-control study was used to verify the normal values, and to explore the cut-off value of UDFF in children with nonalcoholic fatty liver disease, and to further evaluate the degree of fibrosis of NAFLD in children based on SWE measurements.

Outcome:

Ultrasound derived fat fraction

Type:

测量时间点:

在检查前禁食6-8h,20分钟内无剧烈运动

测量方法:

采用彩色多普勒超声诊断仪(ACUSON Sequoia,Siemens Healthineers),使用凸阵探头DAX,频率为 1~3.5MHz。检查前禁食6-8小时,受试者取仰卧位或左侧卧位,探头置于右侧肋间隙,使声束垂直于肝包膜,选取肝实质回声相对均匀的部分(S5或S8段),避开大血管、肋骨声影和肝内强回声灶,将指示线置于肝包膜处并与ROI平行。嘱受试者屏气后进行采集,无法屏气者将在平静呼吸下

Measure time point of outcome:

Fasting for 6-8 hours and no strenuous exercise for 20 minutesbefore the examination.

Measure method:

Color Doppler ultrasound system (ACUSON Sequoia, Siemens Healthineers) is used, and the convex array probe DAX is used for low frequency, with a frequency of 1~3.5MHz. The subject was placed in the supine position, the probe was placed in the right intercostal space, so that the sound beam was perpendicular to the liver capsule, and the part of the liver parenchyma in the S5 or S8 segment with more uniform echo was selected, and the indicator line was placed at the liver capsule and parallel to
