“…Hardware imperfections, such as gradient heating and eddy currents, are further sources of artifacts
6,7 . These effects are particularly evident in gradient echo sequences with long echo times, such as
‐weighted imaging,
2,8 which forms the basis of SWI
9,10 and quantitative susceptibility mapping
11–13 . While imaging at ultra‐high field enhances sensitivity to microscopic susceptibility variations, which improves contrast in both magnitude and phase images,
14,15 the impact of macroscopic perturbations in the background magnetic field also increases with field strength, which is detrimental to image quality
