Recent studies have shown that there is a direct link between the orientation of the nerve
fibers in white matter (WM) and the contrast observed in magnitude and phase images …

Recently reported contrast in phase images of human and animal brains obtained with
gradient-recalled echo MRI holds great promise for the in vivo study of biological tissue …

Purpose Phase images obtained by gradient‐recalled echo (GRE) MRI provide new contrast
in the brain that is distinct from that obtained with conventional T1‐weighted and T2 …

In MRI, structurally aligned molecular or micro‐organization (eg axonal fibers) can be a
source of substantial signal variations that depend on the structural orientation and the …

MRI phase images of the brain exhibit excellent contrast and high signal‐to‐noise ratio. It
has been shown recently that the phase contrast not only depends on a tissue's magnetic …

Phase images obtained with gradient echo MRI provide image contrast distinct from T1-and
T2-weighted images. It is commonly assumed that the local contribution to MRI signal phase …

Heterogeneity of magnetic susceptibility within brain tissues creates unique contrast
between gray and white matter in magnetic resonance phase images acquired by gradient …

Purpose Magnetic resonance T1‐weighted images are routinely used for human brain
segmentation, brain parcellation, and clinical diagnosis of demyelinating diseases. Myelin is …

The image contrast in magnetic resonance imaging (MRI) is highly sensitive to several
mechanisms that are modulated by the properties of the tissue environment. The degree and …

Magnetic resonance imaging has previously demonstrated its potential for indirectly
mapping myelin density, either by relaxometric detection of myelin water or magnetization …
