Implication
Imaging atlas study demonstrates 3D reconstruction and parcellation of major white matter tracts in the human brain, highlighting utility for clinical diagnostics and anatomical education.
Key Points
- Develop two- and three-dimensional atlases of human white matter anatomy using high-resolution diffusion tensor magnetic resonance imaging and tract reconstruction.
- Acquired high-spatial-resolution diffusion tensor MR imaging datasets and performed 3D tract reconstruction of major white matter pathways.
- Coregistered reconstructed tracts onto anatomical MR images to parcel white matter and correlated parcellation maps with diffusion tensor color maps.
- Successfully reconstructed and visualized the 3D trajectories of 17 prominent white matter tracts.
- Delineated anatomical structures identifiable on diffusion tensor images and defined their specific spatial locations across different section levels and orientations.
