1. A method for reducing motion artifacts in magnetic resonance image data acquired from a region of a patient using a magnetic resonance imaging (MRI) device, the method comprising:
performing a scout scan of the region of the patient;
performing a magnetic resonance (MR) measurement of the region of the patient by performing a sequence reordering to acquire MR image data of the region of the patient,
wherein the sequence reordering includes a first reordering type for a center region of k-space and a second reordering type for a remainder of k-space, the second reordering type being different from the first reordering type; and
performing motion correction on the acquired MR image data based on the scout scan to generate corrected MR image data,
wherein the motion correction reduces an influence of a patient motion on the MR image data,
wherein the scout scan has a shorter duration than a duration of the MR measurement and does not exceed 10 seconds.
