Magnetic Resonance Imaging Diffusion Tensor Imaging Diffusion_Tensor_Imaging A type of MRI technique that maps the diffusion of water in three dimensions. Diffusion Tensor Imaging CDISC CTRP DIPG/DMG C1537007 DT-MRI DIFFUSION TENSOR MRI A type of diffusion-weighted magnetic resonance imaging (DW-MRI) that maps the diffusion of water in three dimensions, the principal purpose of which is to image the white matter of the brain, specifically measuring the anisotropy, location, and orientation of the neural tracts, which can demonstrate microstructural changes or differences with neuropathology and treatment.
