Dwi tractography
Diffusion tensor imaging (DTI) is an MRI technique that uses anisotropic diffusion to estimate the axonal (white matter) organization of the brain. Fiber tractography (FT) is a 3D reconstruction technique to assess neural tracts using data collected by diffusion tensor imaging. See more For many, diffusion tensor imaging is synonymous with MRI of the CNS. However, its use for the assessment of highly-organized … See more In fiber tractography imaging, the convention for color coding is as follows: 1. red: transverse fibers 2. green: anteroposterior fibers 3. blue: craniocaudal fibers Fibers with oblique orientation are represented with … See more Some terms 1. diffusion tensor imaging (DTI) provides a quantitative analysis of the magnitude and directionality of water molecules 2. the word tensor indicates the use of a 3x3 matrix … See more http://www.xrayphysics.com/dwi.html
