Imaging characteristics of white matter tract injury in glioma on diffusion tensor imaging
Main Article Content
Abstract
The study was conducted to describe the imaging characteristics of white matter tract injury in preoperative low - grade (LGG) and high - grade gliomas (HGG) on diffusion tensor imaging (DTI). A cross - sectional study was performed from September 2019 to April 2021 on 46 patients with pathology of glioma, who underwent diffusion tension imaging (DTI) before surgery or biopsy. Among the types of lesions of the corticospinal tract, edema and infiltration were the two most common forms with the proportion of 21.7% and 45.7%, respectively. Edema was common in LGG and infiltration was common in HGG. In the language pathways, edema and displacement were common injuries in LGG, infiltration was common in HGG. Disruption was found in 5/6 fiber tracts in HGG and was not seen in LGG. The difference in axonal damage characteristics between two groups of gliomas was statistically significant with p < 0.05. In conclusion, edema and displacement were common in LGG, while the disruption and infiltration axonal were common in HGG.
