By observing the gradually developing characteristics of track density in the area of peritumoral edema, the extent of possible tumor invasion was judged. This may contribute to neurosurgical planning, the postoperative quality of life, and longer survival expectancy. Simultaneously, TDI was able to show the crossing fibers of the tumor part but could not resolve the disturbed diffusion of severe peritumoral edema’s influence on the fibers.
