| PURPOSE : To evaluate whether there was any difference in the brightness of echogenicity on gray scale ultrasound
imaging between the liver with chronic hepatitis and the normal liver using Adobe photoshop 5.0.
MATERIALS and METHODS : Seventy-five patients with pathologically proven chronic hepatitis and twenty normal
volunteers were included in this study. Adobe photoshop 5.0 histogram was used to measure the brightness of
image. The measured brightness of the liver was divided by the brightness of the kidney, and the ratio was calculated
and compared between patients with chronic hepatitis and the normal control groups. In addition, the degree
of fibrosis was also evaluated.
RESULTS : The difference in brightness between the normal liver and live with chronic hepatitis was statistically significant,
but no statistically significant difference was observed between the brightness of the liver and the degree
of fibrosis in the liver.
CONCLUSION : Tissue echo quantification using Adobe Photoshop 5.0 may be a helpful diagnostic method for the
patients with chronic hepatitis. |
