The combination of data acquired with array coils often leads to phase artifacts. The recently-introduced method ‘Prescan-Normalize Adaptive Combine’ (PN-AC) is assessed in terms of non-ΔB0-related contributions and reproducibility with different head positions and compared with a robust multi-echo phase combination approach (called ASPIRE) which yields only ΔB0-related phase. PN-AC was found to generate low noise phase images but introduce non-ΔB0-related contributions to the combined phase. It was robust to motion between the prescan and the main acquisition other than the introduction of arbitrary background phase.
