How can MRI imaging be sensitive to diffusion?
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.
Diffusion MRI. Diffusion tensor imaging. Clinical neurology. Since the first descriptions of nuclear magnetic resonance (MR) in the 1950s, there has been interest in using MR to measure the diffusion properties of water.

Mar 20, 2023 · Diffusion-weighted imaging (DWI) is a form of MR imaging based upon measuring the random Brownian motion of water molecules within a voxel of tissue. In general simplified terms, highly cellular tissues or those with cellular swelling exhibit lower diffusion coefficients.

Jul 23, 2015 · Since its introduction in the mid-1980s, diffusion magnetic resonance imaging (MRI), which measures the random motion of water molecules in tissues, revealing their microarchitecture, has become a pillar of modern neuroimaging.

Dec 1, 2021 · Diffusion MRI has proven itself to be a rapidly evolving field for brain tissue imaging, with developments for both white matter and gray matter. Around since the 1990s, diffusion MRI is an innovative imaging modality that utilizes the diffusive motion of water molecules to distinguish between tissues.
During the last 25 years, diffusion MRI has been extraordinarily successful (with more than 300,000 entries on Google Scholar for diffusion MRI). Its main clinical domain of application has been neurological disorders, especially for the management of patients with acute stroke.
