2-dimensional, Diffusion-weighted Imaging/ Diffusion Tensor Imaging

**Semantic type:** Diagnostic Procedure

**Definition:** 2-dimension, T2-weighted magnetic resonance imaging that uses the diffusion of water molecules to generate contrast in MR images. Diffusion tensor imaging (DTI), a specific type of DWI, can be used to map white matter tractography in the brain.
