摘要
En 中文
White matter damage is a common finding on conventional magnetic resonance diffusion-weighted imaging (DWI) in patients with moderate and severe traumatic brain injury. Diffusion tensor imaging (DTI), a more recent model derived from DWI, allows for the calculation of several diffusion metrics that reflect the strength and direction of water diffusion in the brain. These diffusion metrics can yield important information about the health and integrity of fiber tracts. For example, fractional anisotropy (FA) measures water dispersion along the main axis of fiber tracts with higher FA indicating higher fiber density or myelination, whereas radial diffusivity (RD) measures diffusivity perpendicular to axonal fibers, with higher RD indicating lower tract myelination or potential tract damage. More recently, a growing number of DTI studies have reported changes in diffusion metrics in patients with mild traumatic brain injury (mTBI) including altered FA and RD.
