This article describes an accurate and fast method for fiber orientation mapping using
multidirectional diffusion-weighted magnetic resonance (MR) data. This novel approach utilizes …

Diffusion-weighted magnetic resonance (MR) signals reflect information about underlying
tissue microstructure and cytoarchitecture. We propose a quantitative, efficient, and robust …

Chemically‐fixed nervous tissues are well‐suited for high‐resolution, time‐intensive MRI
acquisitions without motion artifacts, such as those required for brain atlas projects, but the …

There is a need for accurate quantitative non-invasive biomarkers to monitor myelin
pathology in vivo and distinguish myelin changes from other pathological features including …

High-resolution imaging of human autopsy tissues may improve our understanding of in vivo
MRI findings, but interpretation is complicated because samples are obtained by immersion …

Ex vivo biological sample imaging can complement in vivo MRI studies. Since ex vivo studies
are typically performed at room temperature, and samples are frequently preserved by …

Spinal cord lesions detected on MRI hold important diagnostic and prognostic value for
multiple sclerosis. Previous attempts to correlate lesion burden with clinical status have had …

This report introduces a novel method to characterize the diffusion-time dependence of the
diffusion-weighted magnetic resonance (MR) signal in biological tissues. The approach …

Simultaneous PET/MR of the brain is a promising technology for characterizing patients with
suspected cognitive impairment or epilepsy. Unlike CT, however, MR signal intensities do …

Purpose: Investigation of clonal heterogeneity may be key to understanding mechanisms of
therapeutic failure in human cancer. However, little is known on the consequences of …
