Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that enables the measurement of the restricted diffusion of water in tissue in order to produce neural tract images instead of using this data solely for the purpose of assigning contrast or colors to pixels in a cross-sectional image.

Dec 19, 2019 · Diffusion tensor imaging is an advanced magnetic resonance imaging modality that uses the Brownian motion of water molecules to provide data for images. This cutting-edge neuroimaging technique has allowed exploration of the intricate architecture of the brain.

What is Diffusion Tensor Imaging (DTI), and how does it differ from "regular" diffusion-weighed imaging? Diffusion tensor imaging (DTI) comprises a group of techniques where calculated eigenvalues (λ 1, λ 2, and λ 3) and eigenvectors (ε 1, ε 2, and ε 3) are used to create images reflecting various diffusion properties of a tissue.

Diffusion tensor magnetic resonance imaging (DTI) is a relatively new technology that is popular for imaging the white matter of the brain. The goal of this review is to give a basic and broad overview of DTI such that the reader may develop an intuitive understanding of this type of data, and an awareness of its strengths and weaknesses.

Diffusion Tensor Imaging (DTI) is an magnetic resonance imaging‑based neuroimaging technique that makes it possible to estimate the location, orientation, and anisotropy of the white matter tracts of the brain

It gives a step-by-step guide of how to fit the diffusion tensor to data from DTI or HARDI acquisition protocols, how to generate maps of standard markers like mean diffusivity (MD) and fractional anisotropy (FA), and how to generate principal direction and colour FA maps.

In the laboratory frame of reference (x-y-z) we measure diffusion coefficients in 6 unique directional combinations described by the diffusion tensor, D. The measured values of each component depend on the frame of reference.

Mar 6, 2014 · After running the tensor fitting command you will have to check if the vectors were applied correctly. In the below examples we are using Camino's pdview, but you can use any program that allows you to view the tensors. You should check the …

Viewing DTI Images. Certain DTI image files (e.g., V1, the vector image showing the principal diffusion tensor direction) are multi-volume (4D), like FMRI image files. To view such images in DTI Mode, select the image in the Image List and press the Image Info button . This will open the Image Info dialog.
