… In particular, we find sharp differences between the diffusional kurtosis in white and gray
matter, confirming the preliminary results reported by Jensen and Helpern (2). We believe that …

Quantification of non‐Gaussianity for water diffusion in brain by means of diffusional kurtosis
imaging (DKI) is reviewed. Diffusional non‐Gaussianity is a consequence of tissue structure …

Diffusional kurtosis imaging (DKI) is a clinically feasible extension of diffusion tensor
imaging that probes restricted water diffusion in biological tissues using magnetic resonance …

This article presents two related advancements to the diffusional kurtosis imaging estimation
framework to increase its robustness to noise, motion, and imaging artifacts. The first …

Conventional diffusion tensor imaging (DTI) measures water diffusion parameters based on
the assumption that the spin displacement distribution is a Gaussian function. However, …

In this paper a new method is presented for the relative assessment of brain iron concentrations
based on the evaluation of T 2 and T 2 * ‐weighted images. A multiecho sequence is …

Article abstract—Elevated iron levels in the substantia nigra (SN) of the brain in Parkinson's
disease (PD) may mediate lipid peroxidative reactions, promoting SN neuronal death. To …

Brain magnesium was measured in migraine patients and control subjects using in vivo 31‐PhosphorusNuclear
Magnetic Resonance Spectroscopy, pMg and pH were calculated from …

Measuring molecular diffusion is widely used for characterizing materials and living organisms
noninvasively. This characterization relies on relations between macroscopic diffusion …

Patient motion can seriously degrade the quality of diffusion-weighted MR images obtained
using standard 2DFT imaging procedures. The main source of error arises from an MR …
