Analysis of the magneto-rotational instability with the effect of cosmic-ray diffusion
, 2014 We present the results obtained from linear stability analysis and 2.5-dimensional magnetohydrodynamic (MHD) simulations of the magnetorotational instability (MRI), including the effects of cosmic rays (CRs).

Biomimetic phantom for cardiac diffusion MRI [PDF]
Journal of Magnetic Resonance Imaging, 2015 PurposeDiffusion magnetic resonance imaging (MRI) is increasingly used to characterize cardiac tissue microstructure, necessitating the use of physiologically relevant phantoms for methods development. Existing phantoms are generally simplistic and mostly simulate diffusion in the brain. Thus, there is a need for phantoms mimicking diffusion in cardiac

Optimizing Filter-Probe Diffusion Weighting in the Rat Spinal Cord for Human Translation [PDF]
, 2017 Diffusion tensor imaging (DTI) is a promising biomarker of spinal cord injury (SCI). In the acute aftermath, DTI in SCI animal models consistently demonstrates high sensitivity and prognostic performance, yet translation of DTI to acute human SCI has ...

Diffusion MRI: what water tells us about the brain
EMBO Molecular Medicine, 2014 Diffusion MRI has been used worldwide to produce images of brain tissue structure and connectivity, in the normal and diseased brain. Diffusion MRI has revolutionized the management of acute brain ischemia (stroke), saving life of many patients and ...

MRI‐cytometry: Mapping nonparametric cell size distributions using diffusion MRI
Magnetic Resonance in Medicine, 2020 This report introduces and validates a new diffusion MRI‐based method, termed MRI‐cytometry, which can noninvasively map intravoxel, nonparametric cell size distributions in tissues.

Multidimensional diffusion MRI
Journal of Magnetic Resonance, 2017 Principles from multidimensional NMR spectroscopy, and in particular solid-state NMR, have recently been transferred to the field of diffusion MRI, offering non-invasive characterization of heterogeneous anisotropic materials, such as the human brain, at an unprecedented level of detail.

Joint modelling of diffusion MRI and microscopy [PDF]
NeuroImage, 2019 AbstractThe combination of diffusion MRI with microscopy provides unique opportunities to study microstructural features of tissue, particularly when acquired in the same sample. Microscopy is frequently used to validate diffusion MRI microstructure models, addressing the indirect nature of dMRI signals.

Generating Diffusion MRI scalar maps from T1 weighted images using generative adversarial networks
, 2019 Diffusion magnetic resonance imaging (diffusion MRI) is a non-invasive microstructure assessment technique. Scalar measures, such as FA (fractional anisotropy) and MD (mean diffusivity), quantifying micro-structural tissue properties can be obtained ...

Hall diffusion and the magnetorotational instability in protoplanetary discs [PDF]
, 2011 The destabilising effect of Hall diffusion in a Keplerian disc allows the MRI to occur for much lower ionisation levels than would otherwise be possible. However, simulations suggest that the consequences for the saturated state are not as significant as

MR scanner systems should be adequately characterized in diffusion-MRI of the breast. [PDF]
PLoS ONE, 2014 Breast imaging represents a relatively recent and promising field of application of quantitative diffusion-MRI techniques. In view of the importance of guaranteeing and assessing its reliability in clinical as well as research settings, the aim of this ...
