Magnetic susceptibility describes the magnetizability of a material to an applied magnetic
field and represents an important parameter in the field of MRI. With the recently introduced …

Quantitative Susceptibility Mapping (QSM) and Susceptibility Weighted Imaging (SWI) are
MRI techniques that measure and display differences in the magnetization that is induced in …

Abstract Quantitative Susceptibility Mapping (QSM), best known as a surrogate for tissue
iron content, is becoming a highly relevant MRI contrast for monitoring cellular and vascular …

Spatial smoothing is a widely used preprocessing step in functional magnetic resonance
imaging (fMRI) data analysis. In this work, we report on the spatial smoothing effect on task …

The magnetism of hemoglobin–being paramagnetic in its deoxy and diamagnetic in its oxy
state–offers unique opportunities to probe oxygen metabolism in blood and tissues. The …

MRI's transverse relaxation time (T2) is sensitive to tissues' composition and pathological
state. While variations in T2 values can be used as clinical biomarkers, it is challenging to …

Background Pearson correlation (simply correlation) is a basic technique for neuroimage
function analysis. It has been observed that the spatial smoothing may cause functional …

Abnormal cerebral oxygenation and vessel structure is a crucial feature of stroke. An
imaging method with structural and functional information is necessary for diagnosis of …

Dynamic changes of brain-tissue magnetic susceptibility provide the basis for functional MR
imaging (fMRI) via T2*-weighted signal-intensity modulations. Promising initial work on a …

The underlying source of brain imaging by T2*-weighted magnetic resonance imaging (T2*
MRI) is the intracranial inhomogeneous tissue magnetic susceptibility (denoted by χ) that …
