Fig. 2. Box-plots comparing the percent changes of the quantitative parameters in DCE-MRI (LD, TV, PE), DWI (ADC) and PET/CT (SUV max). The mean percent change of the imaging parameters measured by DCE-MRI and PET/CT was decreased more in responders than in non-responders. By contrast, the mean percent change of the ADC value was increased more in the responder group.
