Abstract:
1. A method of mitigating an image artifact resulting from an artifact source using a magnetic resonance imaging (MRI) system, the steps of the method comprising: a) providing an initial magnetic resonance (MR) image acquired with an MRI system; b) identifying in the provided initial MR image, a location of an artifact source at which spins corresponding to the artifact source are located; c) calculating, based on the initial MR image data, a region-of-saturation using the identified location of the artifact source; d) directing the MRI system to perform a magnetic resonance pulse sequence that includes: e) reconstructing from the acquired MR image data, a reconstructed MRI image in which MR image artifacts related to a motion of the spins at the identified location of the artifact source are mitigated from the performance of steps d)i) and d)ii).
