Liver fibrosis in chronic viral hepatitis: An ultrasonographic study

Figure 1 Active cirrhosis. Ultrasonography showed that the hepatic parenchymal echo became coarse and dot-shaped, and the distribution was still homogenous.

Figure 2 Active cirrhosis. Small and sparse fibroitc septa were shown on histology. (HE stain × 100).

Figure 3 Chronic viral hepatitis. On ultrasonography, the hepatic parenchymal echo became coarse and heterogeneous with speckled hyper- and hypoechoic areas.

Figure 4 Chronic viral hepatitis. On histology, focal fatty degeneration foci were shown. (HE stain, × 40).

Figure 5 Chronic viral hepatitis. Ultrasonography showed the hepatic parenchymal echo to be strip-shaped and coarse.

Figure 6 Chronic viral hepatitis. Wide and compact fibrotic septum was shown histologically. (Reticular fiber stain, × 40).
