A magnetic resonance (MR) imaging (MRI) system, the MRI system may include at least one controller which may be configured to: acquire MR information for at least first and second blades of a periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) imaging method; generate, for at least the first and second blades, main field inhomogeneity information based upon the acquired MR information, the main field inhomogeneity information indicating main field inhomogeneity; generate water and fat information individually for at least the first and second blades based upon the acquired MR information and the generated main field inhomogeneity information for the corresponding blade of the first and second blades; and correct at least one of the water and fat information for spatial distortions caused by the main field inhomogeneity or a predetermined chemical shift difference between water and fat.
