Equal-TE Rapid Acquisition with Sequential Excitation (ERASE) is a 3D ultrafast gradient-echo-based Spatiotemporal Encoding (SPEN) imaging technique with a constant TE and high tolerance to main magnetic field () inhomogeneity. However, misregistration of spin isochromat can occur due to large magnetic susceptibility-induced gradients in the prefrontal brain region. Here, we propose that shim improvement by chin-up head tilting can effectively mitigate misregistration in ERASE to realize fast prefrontal brain imaging with much higher image quality than conventional EPI.
