DOI: 10.1002/cne.25121
Abstract: The specific cytopathology that causes abnormal fractional anisotropy (FA) and mean diffusivity (MD) from diffusion tensor imaging (DTI) after neonatal hypoxia‐ischemia (HI) is not completely understood. The panoply of cell types in the brain might… read more here.

DOI: 10.1002/hbm.23681
Abstract: Measures from diffusion MRI have been used to characterize the corticospinal tract in chronic stroke. However, diffusivity can be influenced by partial volume effects from free‐water, region of interest placement, and lesion masking. We collected… read more here.

DOI: 10.1002/mrc.4492
Abstract: Complex materials are ubiquitous in science, engineering and nature. One important parameter for characterising their morphology is the degree of anisotropy. Magnetic resonance imaging offers non‐invasive methods for quantitative measurements of the materials anisotropy, most… read more here.
