Abstract: This paper investigated the value of diffusion tensor imaging (DTI) fiber bundle reconstruction combined with intraoperative ultrasound in the operation of gliomas in brain functional areas. 89 patients with gliomas in brain functional areas were selected, the observation group (n=46) was given DTI fiber bundle reconstruction combined with intraoperative ultrasound, and the control group was given intraoperative ultrasound localization, and both groups were given glioma resection surgery. The results showed that the total tumor resection rate, postoperative Karnofsky functional state (KPS) score, the proportion of symptom improvement, the score of Anderson brain tu(P<0.05). In the observation group, the high-level proportion and anisotropy score (FA) of pathological types in patients with no change or aggravation were higher than those in improved patients (P<0.05), and the apparent diffusion coefficient (ADC) was lower than those in improved patients (P<0.05). The areas under the ROC curve of FA value and ADC value predict the improvement of treatment in the observation group were 0.756 and 0.803, respectively, P<0.05. DTI fiber bundle reconstruction combined with intraoperative ultrasound has good value in the operation of gliomas in brain functional areas, which is worthy of clinical use.
