Fig. 2.

Illustration of a fiber tracking result using an anatomical-seeded cubic ROI. The same protocol like described in Fig. 1 is used except the second ROI which is placed as orange cubic box in the anterior inferior pons (A). Aberrant fibers, clearly not belonging to the CST, are also visualized. Using this results for planning the surgical resection strategy could lead to an unnecessary restricted resection because aberrant fibers running through the tumor might be preserved by the surgeon (B).
