To investigate the characteristics of white matter bundles in normal subjects using 3.0 Tesla magnetic resonance diffusion tensor imaging (DTI). Subject and method: A cross-sectional descriptive study on 30 normal subjects from January 2021 to June 2021 with the aim of characterizing white matter bundles by determining features including number of fibers, fiber length, voxel index, FA, ADC index; performing symmetric comparisons between the two hemispheres and genders comparison. Result: The number of fibers, fiber length and voxel index of the subjects varied largely between different tracts, while the range of values of FA and ADC indexes were more concentrated, but there was still a diversity of figures between different regions and tracts. Moreover, some statistically significant differences between bundles when comparing and comparing by symmetry and genders. Conclusion: This study initially provided the referential parameters for characterizing conduction tracts connecting different brain centers of normal human brain on DTI, which is the basis for further research on brain activities as well as constructing referential thresholds in diagnosis and treatment of neurological diseases.
