TLDR
MAP-MRI represents a new comprehensive framework to model the three-dimensional q-space MR signal and transform it into diffusion propagators, and provides several novel, quantifiable parameters that capture previously obscured intrinsic features of nervous tissue microstructure.About:

Premature white matter aging in patients with right mesial temporal lobe epilepsy: A machine learning approach based on diffusion MRI data.
TL;DR: A brain age prediction model was developed based on diffusion MRI data that showed patients with right MTLE exhibited older brain age than those with left MTLE and predicted age difference (PAD) was correlated with seizure frequency in rightMTLE.

TL;DR: In this paper, diffusion-weighted magnetic resonance imaging (dMRI) was used to estimate age and sex effects on white matter microstructure in a cross-sectional sample of 15,628 adults aged 45-80 years old (47.6% male, 52.4% female).

Generating Diffusion MRI Scalar Maps from T1 Weighted Images Using Generative Adversarial Networks
TL;DR: In this paper, CycleGAN is used to generate synthetic diffusion scalar measures from structural T1-weighted images in a single optimized step, which can be used as a target for nonlinear registration, to correct for geometric distortions common in diffusion MRI.
Journal ArticleDOI
Development of white matter microstructure and executive functions during childhood and adolescence: a review of diffusion MRI studies
TL;DR: In this article, the authors provide a brief overview of diffusion magnetic resonance imaging (dMRI) methods and how they can be used to study white matter and connectivity and review the extant literature examining the links between dMRI indices and executive functions during development.

TL;DR: It is possible to design n=O(Nlog(m)) nonadaptive measurements allowing reconstruction with accuracy comparable to that attainable with direct knowledge of the N most important coefficients, and a good approximation to those N important coefficients is extracted from the n measurements by solving a linear program-Basis Pursuit in signal processing.

Spin diffusion measurements : spin echoes in the presence of a time-dependent field gradient
E. O. Stejskal,J. E. Tanner +1 more
TL;DR: In this article, a derivation of the effect of a time-dependent magnetic field gradient on the spin-echo experiment, particularly in the presence of spin diffusion, is given.

Solving least squares problems
TL;DR: Since the lm function provides a lot of features it is rather complicated so it is going to instead use the function lsfit as a model, which computes only the coefficient estimates and the residuals.
