Patent ID: 7777486

Claim:
A method for magnetic resonance imaging (MRI), comprising: a) applying a magnetic resonance excitation in a MRI apparatus, comprising an imaging excitation and detection system and a controller, which controls the imaging excitation and detection system; b) acquiring a plurality of k-space echoes 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, in the imaging excitation and detection system; c) correcting k-space echo realignment between the even and odd echoes in the controller; d) correcting field inhomogeneity induced artifacts in the controller; e) simultaneously correcting chemical shift induced artifacts between at least two species in the controller; and f) generating an image using the correction k-space echo realignment, correction field inhomogeneity, and correction chemical shift in the controller.
