Quantitative susceptibility mapping in magnetically inhomogeneous tissues. [PDF]
Magn Reson MedAbstractPurposeConventional quantitative susceptibility mapping (QSM) methods rely on simplified physical models that assume isotropic and homogeneous tissue properties, leading to artifacts and inaccuracies in biological tissues. This study aims to develop and evaluate DEEPOLE, a deep learning–based method that incorporates macroscopically nondipolar ...

Functional quantitative susceptibility mapping (fQSM) [PDF]
NeuroImage, 2014 Blood oxygenation level dependent (BOLD) functional magnetic resonance imaging (fMRI) is a powerful technique, typically based on the statistical analysis of the magnitude component of the complex time-series. Here, we additionally interrogated the phase data of the fMRI time-series and used quantitative susceptibility mapping (QSM) in order to ...

Quantitative Susceptibility Mapping of Brain Iron in Healthy Aging and Cognition
NeuroImage, 2023 Quantitative susceptibility mapping (QSM) is a magnetic resonance imaging (MRI) technique that can assess the magnetic properties of cerebral iron in vivo. Although brain iron is necessary for basic neurobiological functions, excess iron content disrupts
