Boxplot of the T1 time and tumor reduction rate in the hepatobiliary phase. (a) Mean T1 time of HCC on plain and postcontrast images (HBP, hepatobiliary phase) with the relevant p-values for the comparison of Gd-EOB-DTPA uptake. (b) Tumor reduction rate between the plain and hepatobiliary phases for well- (G1), moderate (G2) and poorly (G3) differentiated HCCs. Data presented as box plots follow standard Tukey representations. The Wilcoxon signed rank test (#) and the post-hoc pairwise comparisons of the Kruskal–Wallis test (+) were used to compare groups.
