Susceptibility-induced signal dropout and image quality impairment in the gradient-echo based imaging are well known problems in brain MRI at high fields. Here, we experimentally demonstrate the feasibility and benefit of head-tilted brain scan as a means to reduce B₀inhomogeneity and associated gradient echo signal loss in the inferior frontal lobe (IFL), and compare the shim improvement with simulated 3rd order shimming in the whole brain.
