Images and frequency distributions of MR parameters of differentiated and non-differentiated PDAC tumor models. ADC, v _e, and K ^trans images and frequency distributions of a representative BxPC-3 (a), Capan-2 (b), MIAPaCa-2 (c), and Panc-1 (d) tumor, illustrating that the intratumor heterogeneity in these MR parameters was considerable in the four PDAC models. The images refer to a central axial section of the tumors, whereas the frequency distributions are based on the individual voxel values of all tumor sections. Color bars ADC, v _e, and K ^trans scales. Scale bars 2 mm. Vertical lines median values
