Diffusion refers to the net movement or flow of energy or particles, such as atoms, molecules,
and ions, in a physical system. A molecule in a free space undergoes random thermal …

One of the greatest technical challenges for diffusion-weighted imaging (DWI) is overcoming
the phase effects originating from macroscopic motion while simultaneously retaining its …

Diffusion-weighted imaging (DWI) enables the MRI visualization of molecular movements of
water in biological tissues. Molecular diffusion in vivo reflects interactions with …

The signal intensity in MRI depends on the proton density, T1, T2, and T2* relaxation
processes of any ensemble of the spins within each imaging element. Another important …

Magnetic resonance imaging (MRI) is a technique based on the contents and relaxation
features of water in tissues. In basic MRI sequences, diffusion phenomenon of water …

Due to the fast decay rate of the transverse magnetization, diffusion weighting is challenging
in short T2 tissues; only very limited b-values can be achieved before the signal decays to …

Diffusion of water molecules is the target of diffusion-weighted imaging (DW-MRI), although
water mobility in biological systems is a complex process. Diffusion-weighted measurement …

Diffusion weighted imaging has opened new diagnostic possibilities by using microscopic
diffusion of water molecules as a means of image contrast. The directional dependence of …

Diffusion-weighted magnetic resonance imaging (DWI) is a non-invasive MRI technique that
is sensitive to the diffusion of water molecules within the body. Its ability to encode water …

Purpose Diffusion MRI is confounded by the need to acquire at least two images separated
by a repetition time, thereby thwarting the detection of rapid dynamic microstructural …
