A review of magnetic resonance imaging and diffusion tensor imaging findings in mild traumatic brain injury
It is believed that the enhanced sensitivity of newer and more advanced neuroimaging techniques for identifying areas of brain damage in mTBI will be important for documenting the biological basis of postconcussive symptoms, which are likely associated with subtle brain alterations.
Diffusion Tensor Imaging (DTI)-based White Matter Mapping in Brain Research: A Review
While DTI offers a powerful tool to study and visualize white matter, it suffers from inherent artifacts and limitations and provides an efficient tool for comprehensive, noninvasive, functional anatomy mapping of the human brain.

It is suggested that free water is not limited to the borders of the brain parenchyma; it therefore contributes to the architecture surrounding neuronal bundles and may indicate specific anatomical processes.
Diffusion MRI of Structural Brain Plasticity Induced by a Learning and Memory Task
It is found that DTI can be used to define the selective localization of neuroplasticity induced by different tasks and that this process is age-dependent in cingulate cortex and corpus callosum and age-independent in the dentate gyrus.

Widespread white matter microstructural differences in schizophrenia across 4322 individuals: results from the ENIGMA Schizophrenia DTI Working Group
The present study provides a robust profile of widespread WM abnormalities in schizophrenia patients worldwide, and is believed to be the first ever large-scale coordinated study of WM microstructural differences in schizophrenia.

A novel bi-tensor diffusion analysis model was used to indicate that all forms of parkinsonism had elevated free-water in the substantia nigra, and both multiple system atrophy and progressive supranuclear palsy, but not Parkinson's disease, showed a broad network of elevatedFree-water and altered free- water corrected fractional anisotropy that included the basal ganglia, thalamus, and cerebellum.
Hockey Concussion Education Project, Part 3. White matter microstructure in ice hockey players with a history of concussion: a diffusion tensor imaging study.
It is indicated that a history of concussion may result in alterations of the brain's white matter microstructure in ice hockey players and increased FA based on decreased RD may reflect neuroinflammatory or neuroplastic processes of thebrain responding to brain trauma.
