1. A method for correcting an artifact in magnetic resonance imaging (MRI) data, the method comprising:
acquiring plural slices along a slice direction of a scanned region associated with a body part;
identifying a first slice from the acquired plural slices along the slice direction, based on signal intensities of the acquired plural slices, the first slice indicating a location of a metal implant in the body part;
identifying at least one second slice neighboring the first slice; and
combining a signal of the first slice and a signal of the at least one second slice to generate a reconstructed image of the scanned region, wherein at least one slice other than the first slice and the at least one second slice in the acquired plural slices is not used for generating the reconstructed image while the first slice and the at least one second slice are used for generating the reconstructed image.
