Evaluation of Liver Fibrosis Using Texture Analysis on Combined-Contrast-Enhanced Magnetic Resonance Images at 3.0T

Figure 7

Texture versus histologic fibrosis scores. (a) The correlation between the texture and qualitative histology score (average Metavir) is statistically significant with 0.698 () with best-fit line of slope 1.546 and intercept 0.186. (b) Box-plot of texture score versus rounded average Metavir. Spearman’s correlation is significant at (). (c) The correlation between texture and quantitative histology score (percent-fibrosis) is statistically significant with 0.767 (), with best-fit line of slope 0.355 and intercept 6.636. The nonunit slope and nonzero intercept are attributable in part to the regularization procedure employed by the GLM-path algorithm (see text).
