Pre SBRT vs Post SBRT changes in the mean and standard deviation of kinetic model parameters Ktrans (A, C) and ve (B,D) for the three patient groups. These measures refer to the mean and standard deviation over all voxels within the tumor contours of each patient. Circles connected by a line represent an individual patient’s pre- and post-SBRT values. The bars represent the median across patients. The asterisks represent significance (p > 0.05).
