Artifacts and pitfalls in diffusion MRI [PDF]
Journal of Magnetic Resonance Imaging, 2006 AbstractAlthough over the last 20 years diffusion MRI has become an established technique with a great impact on health care and neurosciences, like any other MRI technique it remains subject to artifacts and pitfalls. In addition to common MRI artifacts, there are specific problems that one may encounter when using MRI scanner gradient hardware for ...

Diffusion MRI of the Hippocampus
The Journal of Neuroscience, 2023 The hippocampus is a brain structure that plays key roles in a variety of cognitive processes. Critically, a wide range of neurological disorders are associated with degeneration of the hippocampal microstructure, defined as neurons, dendrites, glial cells, and more.

Diffusion MRI in the heart [PDF]
NMR in Biomedicine, 2015 Diffusion MRI provides unique information on the structure, organization, and integrity of the myocardium without the need for exogenous contrast agents. Diffusion MRI in the heart, however, has proven technically challenging because of the intrinsic non‐rigid deformation during the cardiac cycle, displacement of the myocardium due to respiratory ...

A method for improving the performance of gradient systems for diffusion-weighted MRI [PDF]
, 2007 The MR signal is sensitive to diffusion. This effect can be increased by the use of large, balanced bipolar gradients. The gradient systems of MR scanners are calibrated at installation and during regular servicing visits.
