Abstract

PURPOSE

This study was conducted to evaluate the effect of various degrees of diffuse fatty infiltration of the liver on the hepatic artery resistance index.

METHODS

One-hundred forty subjects were examined using standard color and spectral Doppler sonography protocols. Fatty infiltration of the liver was identified and graded sonographically. The patients were grouped (n = 35 in each of 4 groups) according to the degree of diffuse fatty infiltration of the liver as follows: normal (group 1), mild (group 2), moderate (group 3), and severe (group 4). The resistance index calculated for each patient was the mean of 3 measurements. Mean resistance index of the hepatic artery was then calculated for each group.

RESULTS

The mean resistance index was 0.81 +/- 0.04 for group 1, 0.79 +/- 0.06 for group 2, 0.75 +/- 0.05 for group 3, and 0.73 +/- 0.05 for group 4. We found a statistically significant (p < 0.05) decrease in resistance index when comparing groups 3 and 4 with groups 1 and 2 separately.

CONCLUSIONS

Hepatic artery resistance index decreases as the severity of diffuse fatty infiltration increases.

摘要

目的

本研究旨在评估肝脏不同程度的弥漫性脂肪浸润对肝动脉阻力指数的影响。

方法

采用标准的彩色和频谱多普勒超声检查方案对140名受试者进行检查。通过超声检查识别并分级肝脏脂肪浸润情况。根据肝脏弥漫性脂肪浸润程度将患者分为4组（每组35例）：正常组（第1组）、轻度组（第2组）、中度组（第3组）和重度组（第4组）。为每位患者计算的阻力指数为3次测量的平均值。然后计算每组肝动脉的平均阻力指数。
