Diffusion MRI (dMRI) provides invaluable information for the study of tissue microstructure
and brain connectivity, but suffers from a range of imaging artifacts that greatly challenge the …

We present a review of the characterization of healthy brain aging using MRI with an
emphasis on morphology, lesions, and quantitative MR parameters. A scope review found …

Biophysical models of diffusion in white matter have been center-stage over the past two
decades and are essentially based on what is now commonly referred to as the “Standard …

Tremendous efforts have been made in the last decade to advance cutting-edge MRI
technology in pursuit of mapping structural connectivity in the living human brain with …

We enable the estimation of the per-axon axial diffusivity from single encoding, strongly
diffusion-weighted, pulsed gradient spin echo data. Additionally, we improve the estimation …

To date, we have scarce information about the relative myelination level of different fiber
bundles in the human brain. Indirect evidence comes from postmortem histology data but …

In MRI the transverse relaxation rate, R 2= 1/T 2, shows dependence on the orientation of
ordered tissue relative to the main magnetic field. In previous studies, orientation effects of R …

Purpose Recent studies indicate that T1 in white matter (WM) is influenced by fiber
orientation in B0. The purpose of the study was to investigate the interrelationships between …

Purpose We investigated the correlation, reproducibility, and effect of white matter fiber
orientation for three myelin‐sensitive MRI techniques: magnetization transfer ratio (MTR) …

Biophysical modeling of diffusion MRI (dMRI) offers the exciting potential of bridging the gap
between the macroscopic MRI resolution and microscopic cellular features, effectively …
