Diffusion-Weighted Magnetic Resonance Imaging [PDF]
, 2018 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 molecules is not taken into account although it has a notable influence in the relaxation times, and therefore in the signal intensity of images.

Compensated Diffusion Magnetic Resonance Imaging
Vision Letters, 2015 <p>This paper presents a novel compensated diffusion magnetic resonance<br />imaging (cdMRI) system for improved tissue detail and contrast<br />for screening and diagnosis. The proposed cdMRI system<br />incorporates the intrinsic properties of the MRI apparatus to compensate<br />for artifacts and degradation caused ...

Clinical manifestation and imaging characteristics of transient global amnesia: patent foramen ovale as an underlying factor [PDF]
Journal of Integrative Neuroscience, 2021 Transient global amnesia is not rare, but its etiology remains unknown. Cerebral ischemia is a suspected cause because high signal intensity is observed on diffusion-weighted brain magnetic resonance imaging; however, previous studies have not ...

Magnetic resonance diffusion–weighted imaging: extraneurological applications [PDF]
La radiologia medica, 2006 Diffusion-weighted (Dw) imaging has for a number of years been a diagnostic tool in the field of neuroradiology, yet only since the end of the 1990s, with the introduction of echoplanar imaging (EPI) and the use of sequences capable of performing diffusion studies during a single breath hold, has it found diagnostic applications at the level of the ...
