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. © 2005 Wiley Periodicals, Inc. J Clin Ultrasound 33:95–99, 2005
