How does B-value affect HARDI reconstruction using clinical diffusion MRI data? [PDF]

PLoS ONE, 2015
A number of imaging factors can affect the orientation distribution function (ODF) reconstruction in high angular resolution diffusion imaging (HARDI). The aim of this study was to investigate the effect of the b-value on the HARDI reconstruction and to ...

Heart rate changes in chronically red cell transfusion-dependent patients-A dose-dependent effect of red cell transfusion: A randomized cross-over trial, interim analysis. [PDF]

Transfusion
Abstract Background Restrictive red blood cell transfusion strategies are widely recommended for acute anemia but may not adequately address the needs of chronically anemic patients with transfusion‐dependent myelodysplastic syndromes or myeloproliferative neoplasms.

DIM: A diffusion instability measure for MRI quality assurance. [PDF]

Magn Reson Med
Abstract Purpose The aim of the presented work is to develop a diffusion instability measure (DIM) that can be used in quality assurance. Methods Single‐shot, spin‐echo, echo‐planar imaging HARDI diffusion data sets were collected on a spherical silicone oil phantom with 64 different diffusion directions on a 3T Philips Achieva and a 3T Siemens Cima.X ...

Potential Biomarkers From Positive Definite 4th Order Tensors In Hardi

IEEE International Symposium on Biomedical Imaging, 2021
In this paper, we provide a framework to evaluate new scalar quantities for higher order tensors (HOT) appearing in high angular resolution diffusion imaging (HARDI). These can potentially serve as biomarkers.

High angular resolution susceptibility imaging and estimation of fiber orientation distribution functions in primate brain

NeuroImage, 2023
Uncovering brain-tissue microstructure including axonal characteristics is a major neuroimaging research focus. Within this scope, anisotropic properties of magnetic susceptibility in white matter have been successfully employed to estimate primary ...

Generalized Hardy’s Paradox [PDF]

Physical Review Letters, 2018
Here we present the most general framework for $n$-particle Hardy's paradoxes, which include Hardy's original one and Cereceda's extension as special cases. Remarkably, for any $n\ge 3$ we demonstrate that there always exist generalized paradoxes (with the success probability as high as $1/2^{n-1}$) that are stronger than the previous ones in showing ...

High angular resolution diffusion imaging (HARDI) of porcine menisci: a comparison of diffusion tensor imaging and generalized q-sampling imaging. [PDF]

Quant Imaging Med Surg, 2023
Background Diffusion magnetic resonance imaging (MRI) allows for the quantification of water diffusion properties in soft tissues. The goal of this study was to characterize the 3D collagen fiber network in the porcine meniscus using high angular ...

Discrete Hardy Spaces [PDF]

Journal of Fourier Analysis and Applications, 2014
The authors summarize the contents of this paper in the abstract as follows: We study the boundary behavior of discrete monogenic functions, i.e. null-solutions of a discrete Dirac operator, in the upper and lower half space. Calculating the Fourier symbol of the boundary operator we construct the corresponding discrete Hilbert transforms, the ...

Converting Multi-shell and Diffusion Spectrum Imaging to High Angular Resolution Diffusion Imaging

Frontiers in Neuroscience, 2016
Multi-shell and diffusion spectrum imaging (DSI) are becoming increasingly popular methods of acquiring diffusion MRI data in a research context. However, single-shell acquisitions, such as diffusion tensor imaging (DTI) and high angular resolution ...
