Assessment of liver volume with computed tomography and comparison of findings with ultrasonography.
OBJECTIVE
In this study, we aimed to investigate the impact of non-alcoholic hepatic steatosis on the liver volume. As investigating hepatic steatosis, we utilized computed tomography (CT) to determine the degree of steatosis and we utilized hepatobiliary ultrasonography (USG) for densitometry and correlation.


METHODS
As hepatosteatosis group, 35 patients over 18 years of age and whose abdominal CT scans were requested by several clinics and performed routinely were included in this study, and as control group, 40 healthy subjects without hepatosteatosis (clinically and radiologically) and correlated with hepatosteatosis group in terms of age and gender were included in this study. CT densitometry and liver attenuation index (LAI) of all individuals who participated in our study were calculated, and contrast images of patients were transferred to CT-Volume Software (Siemens Syngo Multimodality Workplace; Version VE52A). In this study, interactive and automated volume measurement techniques were used together. The volumes were measured separately in patient and control group.


RESULTS
In this study for each stage in USG, there was found a direct correlation in terms of LAI and volume, and this correlation was statistically significant (p < 0.01). Furthermore, statistical significance between size and USG stage draws attention (p < 0.05). A significance relationship between USG stage and age could not be determined.


CONCLUSIONS
As a result, we have reached the conclusion that CT densitometry can be used as an assistive technique along with USG to determine the degree of steatosis in the non-alcoholic fatty liver disease, and there is a positive linear correlation between the liver size and volume, and liver volume increases in the non-alcoholic fatty liver disease.
