Abstract: Described here are systems and methods for correcting magnetic resonance data for off-resonance effects arising from the use of a multi-echo echo planar imaging (“EPI”) pulse sequence. Reference data are acquired, from which phase maps are computed in a distorted coordinate space associated with geometric distortions associated with the multi-echo EPI acquisition. Images reconstructed from the magnetic resonance data are demodulated using the distorted phase maps to produce distortion free images of the subject. Advantageously, the systems and methods can be used to reconstruct distortion free images from magnetic resonance data that is otherwise prone to image distortions from off-resonance errors, including data acquired from hyperpolarized nuclear spin species such as hyperpolarized carbon-13.
