Problem: The importance of FACT algorithm for surgical planning has been substantiated in the past. No clinical experience is available for probability maps. This work aimed to compare FACT and probability maps in human gliomas. Methods: 10 patients with human gliomas (4 WHOII, 6 WHOIII) received both fiber tracking methods of the motor fibers arising from fMRI derived seed points. Results: Probability maps were successful in all cases.
