Susceptibility‐weighted imaging (SWI) is a magnetic resonance imaging (MRI) technique
that enhances image contrast by using the susceptibility differences between tissues. It is …

Although iron is crucial for neuronal functioning, many aspects of cerebral iron biology await
clarification. The ability to quantify specific iron forms in the living brain would open new …

Background This study explores the magnetostatic properties of the Alzheimer's disease
brain using a recently proposed, magnetic resonance imaging, postprocessed contrast …

Previous authors have shown that the transverse relaxivity R2* and frequency shifts that
characterize gradient echo signal decay in magnetic resonance imaging are closely …

This review discusses the major contributors to the subtle magnetic properties of brain tissue
and how they affect MRI contrast. With the increased availability of high‐field scanners, the …

Recent advances in high-field MRI have dramatically improved the visualization of human
brain anatomy in vivo. Most notably, in cortical gray matter, strong contrast variations have …

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

Recent advances in high-field (≥ 7 T) MRI have made it possible to study the fine structure
of the human brain at the level of fiber bundles and cortical layers. In particular, techniques …

Since the introduction of 4 T human systems in three academic laboratories circa 1990,
rapid progress in imaging and spectroscopy studies in humans at 4 T and animal model …

T2*-weighted gradient-echo MRI images at high field (≥ 7T) have shown rich image
contrast within and between brain regions. The source for these contrast variations has been …
