|G*| and φ values of the selected regions of interest (ROIs) as well as the parameter ratios of tumor ROI to healthy tissue ROI (normal appearing white matter) of the 22 patients included in the study.

The standard deviations of |G*| and φ within the tumor indicating the tumor heterogeneity are given in the brackets.tumor: region of GB, HAM: region of homogeneous appearing matter, healthy: region of normal appearing white matter, perifocal: ring of tissue obtained by dilatation of the tumor region, edema: region of edematous tissue.|G*| and φ values of the selected regions of interest (ROIs) as well as the parameter ratios of tumor ROI to healthy tissue ROI (normal appearing white matter) of the 22 patients included in the study.
