This work aimed to demonstrate an essential phase shift ε 0 for better quantifying R 2 and R
2* in human brain white matter (WM), and to further elucidate its origin related to the …

Purpose To overcome some limitations of previous proton orientation-dependent transverse
relaxation formalisms in the human brain white matter (WM) by a generalized magic angle …

Abstract Diffusion tensor MRI (DT-MRI) remains the most commonly used approach to
characterise white matter (WM) anisotropy. However, DT estimates may be affected by tissue …

We compare T2-relaxation and diffusion tensor data from normal human brain. The
relationships between myelin-water fraction (MWF) and various diffusion tensor measures …

A high degree of structural order by white matter (WM) fibre tracts creates a physicochemical
environment where water relaxations are rendered anisotropic. Recently, angularly …

The anisotropy of brain white matter microstructure manifests itself in orientational-
dependence of various MRI contrasts, and can result in significant quantification biases if …

Purpose To demonstrate that rotationally invariant measures of the diffusion anisotropy on a
microscopic scale can be mapped in human brain white matter in vivo. Methods Echo …

Diffusion‐tensor imaging is widely used to characterize diffusion in biological tissue,
however, the derived anisotropy information, eg, the fractional anisotropy, is ambiguous. For …

In diffusion tensor magnetic resonance imaging (DT-MRI), limitations concerning complex
fiber architecture (when an image voxel contains fiber populations with more than one …

The intra-axonal axial diffusivity (D a) has a prominent role in describing and modeling the
white matter microstructure, but cannot be obtained from regular diffusion tensor imaging …
