Figure 3. Quantification of hepatic fibrosis. (a) Photomicrograph of a liver section from a cirrhosis patient shows regenerating nodules of various sizes encircled by fibrotic septa (blackish areas) including the portal triads. The fibrotic area is 24.6% of the total area. (b) Photomicrograph of a liver section from a normal liver patient shows minimal deposition of collagen around the portal triads. The fibrotic area is 5.2% of the total area. (Sirius Red/Fast Green staining; original magnification, scale=1 mm).
