Keyword: DWI
DWI - diffusion-weighted magnetic resonance imaging (DW-MRI or DWI) detects the random movement of water molecules within regions of the brain (known as diffusion) to create images non-invasively. Highly cellular tissue, or tissue that is exhibiting cellular swelling, will restrict the movement of water molecules. We can detect that restriction of movement of water molecules using DWI to create contrast images of the brain. In a clinical setting, this method is extremely sensitive at detecting acute stroke. Within neuroscience research, it is most commonly used to trace out the mathematical representations of axons that form between neurons in different locations (tractography) and to examine the fine-scale structure of the brain, the neuronal microstructure.
