Hepatic enhancement and signal intensity analysis on magnetic resonance imaging as prognostic biomarkers in advanced chronic liver disease

Figure 4 Mean global hepatobiliary-phase signal intensity across Functional Liver Imaging Score categories. The bar chart illustrates a significant and progressive increase in mean global hepatobiliary signal intensity (SI) with higher Functional Liver Imaging Score (FLIS) (P < 0.001). The bar chart illustrates a substantial and progressive increase in mean global hepatobiliary SI, accompanied by higher FLIS scores (P < 0.001). Error bars represent the 95% confidence interval (95%CI). Post hoc Tukey’s honest significant difference analysis confirmed statistically significant differences between distant and adjacent FLIS categories, including FLIS 4 vs 6 and FLIS 5 vs 6. These results indicate that hepatobiliary-phase SI correlates closely with hepatocellular function as reflected by the FLIS score.
