Multidimensional Diffusion MRI Methods With Confined Subdomains
- Computer ScienceFrontiers in Physics
- 2022
This work provides the basis for incorporating a model that takes confinement into account and possesses a diffusion time-dependence closer to that of restricted diffusion into two multidimensional diffusion MRI methods, and attempts to recover a confinement tensor distribution (CTD) on a human brain dataset.
A new framework for MR diffusion tensor distribution
- MathematicsScientific Reports
- 2021
A Monte Carlo scheme is used to synthesize realistic numerical diffusion tensor distribution (DTD) phantoms and invert the MR signal and a family of invariant parameters which characterize microscopic shape, size and orientation heterogeneity within a voxel are presented.
Estimation of free water-corrected microscopic fractional anisotropy
- MedicinemedRxiv
- 2023
Simulations and in vivo acquisitions indicated that the FWE method may be a feasible technique for measuring microscopic fractional anisotropy and other indices with greater specificity to neural tissue characteristics than conventional methods.

Accuracy and precision of statistical descriptors obtained from multidimensional diffusion signal inversion algorithms
- MathematicsNMR in biomedicine

All inversion techniques share similar precision (except for a lower precision of the two‐dimensional Monte Carlo inversion) but differ in terms of accuracy, which is found to be significant in most systems investigated.

From the study of six healthy adult subjects, the excess diffusional kurtosis is found to be significantly higher in white matter than in gray matter, reflecting the structural differences between these two types of cerebral tissues.

It is argued that the diffusional kurtosis is sensitive to diffusional heterogeneity and suggested that DKI may be useful for investigating ischemic stroke and neuropathologies, such as Alzheimer's disease and schizophrenia.
Effective medium theory of a diffusion‐weighted signal
- MathematicsNMR in biomedicine
- 2010
A general approach to quantify the medium heterogeneity when it is much finer than the sample size or the imaging resolution is developed, based on the treatment of the medium statistically in terms of the correlation functions of the local parameters.
Equivalence of double and single wave vector diffusion contrast at low diffusion weighting

It is shown that, under many circumstances, the same type of information can be obtained by combining two or more standard single pulse diffusion‐weighted experiments acquired at different diffusion times.
