A method for performing magnetic resonance imaging of an object is provided. The method includes acquiring MR signals from the object via an MRI system, and generating correct T2 values and incorrect spin densities by applying a fitting model to the MR signals. The method further includes generating one or more correction factors, and generating corrected spin densities based at least in part on the incorrect spin densities and the one or more correction factors. The one or more correction factors are based at least in part on the correct T2 values and a bandwidth of a fat suppression signal applied to the object.
