What is diffusion tensor imaging?
Diffusion tensor imaging (DTI) is an MRI-based technique used to visualize and analyze the microstructure of brain tissue.
How does DTI help in understanding neurological disorders?
DTI allows researchers to identify changes in white matter integrity that are associated with various neurological conditions.
What are fractional anisotropy (FA) statistics?
FA statistics quantify the directional dependence of water diffusion in brain tissue, providing insights into white matter integrity.
What is the significance of whole brain-based spatial statistics (WBSS)?
WBSS enables voxel-wise comparisons across different subject groups, facilitating the detection of pathological differences in brain structure.
What are TrackWise fractional anisotropy statistics (TFAS)?
TFAS complements voxel-wise analysis by comparing brain structures defined through fiber tracking, enhancing the understanding of white matter pathways.
