Diffusion tensor imaging (DTI) is a magnetic resonance-based modality that characterises the directional movement of water molecules in neural tissue. By modelling diffusion as a tensor, it provides ...
Diffusion-weighted imaging (DWI) is a key contrast mechanism in MRI which allows for the assessment of microstructural properties of brain tissues by measuring the displacement of water molecules.
The brain’s waste-clearing system significantly declines in function with repeated head impacts, according to a new study of cognitively impaired professional boxers and mixed martial arts fighters.
