A method for magnetic resonance imaging (MRI) is provided. A magnetic
resonance excitation is provided. A plurality of k-space echoes is
acquired bi-directionally wherein at least one echo is an even echo
acquired in a first direction and at least one echo is an odd echo
acquired in a second direction opposite from the first direction. K-space
echo realignment is corrected between the even and odd echoes. Field
inhomogeneity induced artifacts are corrected. Chemical shift induced
artifacts between at least two species are corrected.
