In this work, we present an optimized, scan-time efficient multi-echo MP2RAGE sequence (ME-MP2RAGE) for improved brain segmentation at ultra-high field. Apart from removing B1-, M0, and T2* dependencies (MP2RAGE features), the proposed method removes susceptibility induced image distortions along the readout direction. Additionally, an optimized reordering scheme was implemented for scan-time optimization.
