Figure 1.

The quantitative MRI texture features to characterize underlying tumor structure. Representative MRI images for PDAC tumors from untreated control and treatment (DC vaccine and dinaciclib) groups were presented in (A). The heatmap representation demonstrates the association between computed texture features identified following correlation analysis (B). The z-scores of candidate features and diagnostic accuracies (ACC) of each variable in a univariate model were presented in (C). Multivariable models are performed to improve early detection of treatment effects on tumor tissues due to observed lower accuracy with univariate models.
