Correlation between fibrosis ratio and the intensity difference in the 5-, 10- and 15-min phases. a 5-min phase: Pearson’s correlation coefficient was r = 0.56 (P < 0.0001). b 10-min phase: Pearson’s correlation coefficient was r = 0.67 (P < 0.0001). c 15-min phase: Pearson’s correlation coefficient was r = 0.76 (P < 0.0001). The intensity difference in the 15-min phase showed the closest correlation with the fibrosis ratio among the three phases
