<unk> -weighted magnetic resonance imaging (DWI or DW-MRI) is the use of specific<unk>  sequences as well as software that generates images from the resulting data that uses the<unk>  of water molecules to generate contrast in MR images. It allows the mapping of the<unk>  process of molecules, mainly water, in biological tissues, in vivo and non-invasively. Molecular<unk>  in tissues is not random, but reflects interactions with many obstacles, such as macromolecules, fibers, and membranes. Water molecule<unk>  patterns can therefore reveal microscopic details about tissue architecture, either normal or in a diseased state. A special kind of DWI,<unk>  tensor imaging (DTI), has been used extensively to map white matter tractography in the brain.
