2. Figure 1
A 65-year-old man with hepatitis C. The Child–Pugh class was A. HCC was found in segment 6 (not shown). (a) The ROI was placed on the right lobe of the liver on an HBP image. The increase ratio of LMR was (b) Histogram of the signal intensity of NLP demonstrated a peaked distribution with high kurtosis (3.195) and low skewness (−1.279). This case was categorised into the highK/lowS category.

A 57-year-old man with hepatitis C. The Child–Pugh class was A. HCC was not identified. (a) The ROI was placed on the right lobe of the liver on an HBP image. The increase ratio of LMR was (b) The histogram of signal intensity of the NLP demonstrated a positive distribution but relatively lower kurtosis (0.522) and high skewness (0.056). This case was categorised into the lowK/highS category.

5. Figure 4
Schematic diagram of changes from baseline (broken line) to the histographic pattern typical of the highK/lowS category (solid line). The histogram of the highK/lowS category shows a peaked distribution with a loss of the shoulder accompanied by a longer and thicker left tail. In the highK/lowS category, hepatocytes (or groups of them) with less contrast medium uptake ability form a longer and thicker tail at the left. In contrast, highly functional hepatocytes (or groups of them) with greater contrast uptake ability build a sharper peak. In such conditions, these accelerated or hyperplastic hepatocytes could have many opportunities to undergo oncogene mutation.
