Abstract

Purpose: To investigate whether there is any effect of preprandial and postprandial states of patients on Ultrasound-derived fat fraction(UDFF) in liver fat content measurement.

Methods: A retrospective study was conducted on 1596 patients who underwent UDFF from January to September 2024; UDFF measurements were performed by a sonographer, who repeated each measurement 5 times before and after meals, respectively, and finally expressed them as the mean; then paired t-tests and analyses of variance (ANOVA) were used to compare the differences in preprandial and postprandial UDFF and Auto p-SWE( Auto point shear wave elastography) values among groups, and linear regression was used to analyze the differences in preprandial and postprandial UDFF and Auto p-SWE values between each group.

Results: The study enrolled 1036 patients(491 males and 545 females), aged 18-89 years, mean age (56.50 ± 14.67) years. The differences in UDFF and Auto p-SWE values between the group eating protein and fatty foods (n = 613) and the group eating light foods (n = 423) were not statistically significant (p > 0.05); the differences in UDFF and Auto p-SWE values between the group with a body mass index(BMI) < 25 kg/m2 (n = 703) and the group with a BMI ≥ 25 kg/m2 (n = 333) were statistically significant (p < 0.05). Preprandial and postprandiall UDFF and Auto p-SWE values were highly positively correlated in the eating group, the protein and greasy food group, and the light food group (r = 0.985, 0.983, 0.988, r = 0.834, 0.849, 0.810, all p < 0.001).

Conclusions: UDFF has good consistency in the measurement of liver fat content in preprandial and postprandial states.

肝脏脂肪含量测量中超声脂肪含量的影响变量：餐前和餐后状态。

目的：探讨患者餐前和餐后状态对肝脏脂肪含量测量中超声脂肪分数（UDFF）的影响。方法：对2024年1 - 9月行UDFF的1596例患者进行回顾性研究；UDFF测量由超声医师进行，每项测量分别在餐前和餐后重复5次，最后表示为平均值；采用配对t检验和方差分析比较各组间餐前和餐后UDFF和Auto p-SWE值的差异，采用线性回归分析各组间餐前和餐后UDFF和Auto p-SWE值的差异。结果：纳入1036例患者，其中男性491例，女性545例，年龄18 ~ 89岁，平均年龄（56.50±14.67）岁。蛋白类和脂肪类食物组（n = 613）与清淡类食物组（n = 423） UDFF和Auto p- swe值差异无统计学意义（p < 0.05）；体重指数（BMI）组间UDFF和Auto p-SWE值的差异结论：UDFF测量餐前和餐后肝脏脂肪含量具有良好的一致性。

期刊介绍： Abdominal Radiology seeks to meet the professional needs of the abdominal radiologist by publishing clinically pertinent original, review and practice related articles on the gastrointestinal and genitourinary tracts and abdominal interventional and radiologic procedures. Case reports are generally not accepted unless they are the first report of a new disease or condition, or part of a special solicited section. Reasons to Publish Your Article in Abdominal Radiology: · Official journal of the Society of Abdominal Radiology (SAR) · Published in Cooperation with: European Society of Gastrointestinal and Abdominal Radiology (ESGAR) European Society of Urogenital Radiology (ESUR) Asian Society of Abdominal Radiology (ASAR) · Efficient handling and Expeditious review · Author feedback is provided in a mentoring style · Global readership · Readers can earn CME credits
