This paper describes a new NMR imaging modality--MR diffusion tensor imaging. It consists
of estimating an effective diffusion tensor, Deff, within a voxel, and then displaying useful …

With diffusion tensor MRI one has access to the organization in space of tissue
microstructural components. This outstanding potential adds, however, another layer of …

The apparent diffusion tensor (ADT) imaging method was extended to account for multiple
diffusion components. A biexponential ADT imaging experiment was used to obtain …

The diagonal and off-diagonal elements of the effective self-diffusion tensor, D eff, are
related to the echo intensity in an NMR spin-echo experiment. This relationship is used to …

This article treats the theoretical underpinnings of diffusion‐tensor magnetic resonance
imaging (DT‐MRI), as well as experimental design and data analysis issues. We review the …

Methods are presented to map complex fiber architectures in tissues by imaging the 3D
spectra of tissue water diffusion with MR. First, theoretical considerations show why and …

Diffusion NMR is the only method available today that noninvasively provides information on
molecular displacements over distances comparable to cell dimensions. This information …

Quantitative-diffusion-tensor MRI consists of deriving and displaying parameters that
resemble histological or physiological stains, ie, that characterize intrinsic features of tissue …

The diffusion of water molecules inside organic tissues is often anisotropic (1). Namely, if
there are aligned structures in the tissue, the apparent diffusion coefficient (ADC) of water …

The methods of group theory are applied to the problem of characterizing the diffusion
measured in high angular resolution MR experiments. This leads to a natural representation …
