    “…Quantitative susceptibility mapping (QSM) facilitates mapping of the bulk magnetic susceptibility of tissue from the phase of complex gradient echo (GRE) MRI data. QSM phase processing combined with an [Formula: see text] model of magnitude of multiecho gradient echo data ([Formula: see text]) allows separation of dia- and para-magnetic components (e.g., myelin and iron) that contribute constructively to [Formula: see text] value but destructively to the QSM value of a voxel. …”

    “…PURPOSE: To assess errors associated with EPI‐accelerated intracardiac 4D flow MRI (4DEPI) with EPI factor 5, compared with non‐EPI gradient echo (4DGRE). METHODS: Three 3T MRI experiments were performed comparing 4DEPI to 4DGRE: steady flow through straight tubes, pulsatile flow in a left‐ventricle phantom, and intracardiac flow in 10 healthy volunteers. …”
