TL;DR: The aim of the 2016 quantitative susceptibility mapping (QSM) reconstruction challenge was to test the ability of various QSM algorithms to recover the underlying susceptibility from phase data faithfully.
Journal ArticleDOI

TL;DR: The purpose of this paper is to extend the single-subject Eve atlas from Johns Hopkins University, which currently contains diffusion tensor and T1-weighted anatomical maps, by including contrast based on quantitative susceptibility mapping.
Journal ArticleDOI

J.M.G. van Bergen,Jun Hua,Paul G. Unschuld,Issel Anne L. Lim,Craig K. Jones,Russell L. Margolis,Christopher A. Ross,P. C. M. Van Zijl,Xu Li +8 more
TL;DR: The significant magnetic susceptibility differences between subjects with premanifest Huntington disease and controls and their correlation with genetic burden scores indicate the potential use of magnetic susceptibility as a biomarker of disease progression in premanfold Huntington disease.
Journal ArticleDOI
Imaging Electrical Impedance From Acoustic Measurements by Means of Magnetoacoustic Tomography With Magnetic Induction (MAT-MI)
TL;DR: The present computer simulation results suggest that MAT-MI can reconstruct conductivity images of biological tissue with high spatial resolution and high contrast and in the present simulation study, a two-layer spherical model is used.
Journal ArticleDOI

TL;DR: Computer simulations show that with a practical head rotation angle of around 20°-30°, four head orientations suffice to reproducibly reconstruct the susceptibility tensor with good accuracy, and this approach is tested on whole brain 1 × 1 ×1 mm(3) frequency data acquired from five healthy subjects at 7 T.
