Diffusion-weighted magnetic resonance imaging (DWI or DW-MRI) is the use of specific MRI sequences as well as software that generates images from the resulting data that uses the diffusion of water molecules to generate contrast in MR images.

Nov 12, 2023 · 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.

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.

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.

Oct 1, 2021 · In this review, we present the basic physical principles behind diffusion imaging and provide an overview of the current diffusion techniques, including standard and advanced techniques as well as their main clinical applications.

"Diffusion Tensor Imaging is a cutting edge imaging technique that provides quantitive information with which to visualize and study connectivity and continuity of neural pathways in the central and peripheral nervous system in vivo." -Basser et al, 2000.

Feb 18, 2024 · What is diffusion tensor imaging? What metrics can be derived from DTI? Diffusion tensor imaging or “DTI” refers to images describing diffusion with a tensor model. DTI is derived from preprocessed diffusion weighted imaging (DWI) data.

Nov 12, 2023 · DTI is a variant of diffusion-weighted imaging (DWI) that utilizes a tissue water diffusion rate for image production. The first application of DWI to the human brain was performed in 1986 and since has become the gold standard for detecting acute stroke.

SwiftSketch is a diffusion-based model for object sketching that offers several key benefits: It generates vector sketches, which are resolution-independent, highly editable, and effectively capture the sequential and abstract nature of sketches.; It operates efficiently, generating a single sketch in under a second.; It generalizes effectively across a diverse range of object classes.

Oct 8, 2015 · In DTI 101 we described how diffusion tensor imaging estimates brain microstructure by modeling diffusion of water in the brain. We briefly discuss that this is done by using ellipsoid or ball shaped tensors. This leads to the question; what is a tensor?
