Abstract

Diffusion tensor imaging (DTI) is capable of noninvasive white matter fiber tract reconstruction and shows changes in the white matter, as well as the relationship between glioma and other structures. DTI helps to improve surgical outcomes and allows maximal safety tumor resection in functional areas, especially motor function areas. We did a prospective study with 50 patients from August 2021 to August 2022 in Neurosurgical Center, Viet Duc Hospital. We found that high-grade gliomas are more likely to have infiltrative and disrupted lesions of the pyramid tract on tension diffusion magnetic resonance imaging, whereas low-grade gliomas commonly contact or displace the pyramid tract. Postoperative muscle strength scores improved and preserved in 90% of patients, while unchanged or improved mRS scores accounted for 86%. The utilization of diffusion tensor imaging and intraoperative neuro-navigation in microsurgery of gliomas is valuable and beneficial in the preservation of neurological function and improvement of patient outcomes.
