Multi-echo gradient echo MR imaging enables the generation of quantitative B₀, fat fraction and R₂* maps, from which tissue can be characterized. When applied to cardiac imaging these methods face the challenge presented due to the large susceptibility differences between lung and heart. We present a novel post-processing pipeline for multi-echo GRE phase images that processes the phase data prior to channel combination to enable generation of robust quantitative cardiac maps enabling accurate tissue visualization and characterization.
