PURPOSE : The purpose of this study was to evaluate the efficacy of computer-aided tissue echo quantification tech-nique
in the differentiation of diffuse liver diseases.
MATERIALS and METHODS : Sixty-five patients with chronic liver disease including chronic hepatitis in 21 patients,
fatty liver in 11, and liver cirrhosis in 33, and 55 normal volunteers were included in this study. The sonographic
images by the Sono-PACS(MARO, Seoul) was recalled and the analysis was done for the hepatic parenchymal
coarseness by the program using Visual C++. Difference histogram variation(DHV), edge density(ED) & iner-tia
of cooccurrence matrix(ICM) were used as the coarseness index.
RESULTS : These three indexes were statistically significant(p <0.05) in the differentiation of these
four groups. The accuracy of the differentiation between any two of four groups was 83.0%. The accuracy of the
differentiation of these four groups was 70.8% at the same time.
CONCLUSION : The computer-aided tissue echo quantification technique is a complementary study for the differentiation
of diffuse liver diseases. |
