Reduction of Static Off-Resonance Artifacts in T2*-Weighted Gradient-Echo MRI

A reconstruction method is presented to reduce off-resonance induced artifacts in gradient-echo MRI. The method reconstructs the magnetization without the off-resonance induced phase and in this way reduces the effects of intra-voxel dephasing. The method is applied to simulations and volunteer scans, showing reduced signal voids and improved homogeneity in R2*-maps.
