Final answer:
Diffusion Tensor Imaging (DTI) is a medical imaging technique that uses magnetic resonance imaging (MRI) to visualize the movement of water molecules in the brain's white matter.
Step-by-step explanation:
Diffusion Tensor Imaging (DTI) is a medical imaging technique that uses magnetic resonance imaging (MRI) to visualize the movement of water molecules in the brain's white matter. It measures the direction and magnitude of water diffusion in order to map the pathways of nerve fibers in the brain. By tracking the diffusion of water molecules, DTI can provide information about the structural integrity and connectivity of different brain regions.
