illustrates the process of kinetic intra and peri-tumor heterogeneity characterization. (A) Axial last-phase ultrafast T1-enhanced DCE MRI scan. (B) Tumor 3D segmentation display. (C) Intra-tumoral heterogeneity subregion. (D) High-resolution ultrafast DCE-MRI based time-signal intensity curve in the intra-tumor. (E) Peri-tumoral heterogeneity subregion. (F) High-resolution ultrafast DCE-MRI based time-signal intensity curve in the peri-tumor.
