Abstract
Embodiments of the present invention provide a magnetic resonance imaging method and system and a computer-readable storage medium. The method comprises: performing pre-scanning, wherein a first sequence and a second sequence are separately performed on a plurality of slices; in the first sequence, two echoes are continuously obtained to respectively obtain first image data and second image data having a first phase offset; in the second sequence, two echoes are continuously obtained to respectively obtain third image data and fourth image data having a second phase offset, the first phase offset and the second phase offset having opposite directions but the same angle; obtaining a plurality of radio-frequency field maps respectively corresponding to the plurality of slices based on the first image data and the second image data, and obtaining a plurality of static magnetic field maps respectively corresponding to the plurality of slices based on at least one of the following two groups: a first image and a third image, and a second image and a fourth image; and calculating formal scanning parameters suitable for a corresponding slice based on at least one of the following two comp…
