The effects of b) applying ΔfIR alone and c) - d) both applying ΔfIR and changing ΔtIR of the adiabatic inversion pulse on the artefact reduction compared to a) the original parameters from MPRAGE in inferior frontal area (top, ΔB0 >>0) and anterior temporal lobes (bottom, ΔB0 <<0) shown on the T1w/PDw images. The hyperintensities seen on the frontal lobe in a) and temporal lobe in (b) are largely reduced in c) and eliminated in d). The red arrows indicate the brain areas with the artefacts.
