1. A method for magnetic resonance imaging (MRI) comprising:
performing with an MRI scanner a spoiled gradient-recalled (SPGR) MRI scan using an SPGR acquisition sequence to produce MRI data; and
reconstructing an MRI image from the MRI data;
wherein performing the SPGR MRI scan comprises playing an interleaved-randomized spoiler (IRS) gradient after every M-th acquisition block of the SPGR acquisition sequence, where M≥2, and where an absolute area of the IRS gradient is randomized between zero and a maximum gradient area achievable on the MRI scanner.
