Diffusion Tensor Imaging (DTI) and Connectomics
Diffusion Tensor Imaging (DTI) measures the movement of water molecules along white matter tracts. In 2026, this has evolved into "Whole-Brain Connectomics," where we map the brain's entire structural wiring diagram.
By analyzing the "Fractional Anisotropy" (the directionality of water flow), clinicians can detect "invisible" injuries in Traumatic Brain Injury (TBI) patients. If the water diffusion is isotropic (moving in all directions) rather than following the nerve fiber, it indicates a tear in the neural insulation (myelin).
