Figure 2:

CT scans show examples of automated liver Couinaud segment measurements. Automated segmentation of the eight liver Couinaud segments (I–VIII) in four different stages of liver fibrosis according to the METAVIR scale from dataset 1, shown on axial contrast-enhanced CT scans: F1 (54-year-old man with chronic hepatitis C virus [HCV] infection), F2 (51-year-old man with HCV infection), F3 (46-year-old man with chronic HCV infection), and F4 (55-year-old woman with chronic HCV infection). The liver segmental volume ratio (LSVR) was larger in higher grades. *LSVR = a ratio of the volume of segments I–III to segments IV–VIII.
