Abstract
A method to compensate for chemical shift displacement includes, prior to applying an imaging pulse sequence to acquire MRI data of a subject, applying a first saturation pulse within a slice location of an imaging volume of the subject in which the MRI data is to be acquired, wherein the first saturation pulse results in a first chemical shift displacement between water and fat in a first spatial saturation band. The method also includes, prior to applying the imaging pulse sequence, subsequently applying a second saturation pulse within the slice location, wherein the second saturation pulse results in a second chemical displacement between the water and the fat in a second spatial saturation band that results in a final spatial saturation band being free of chemical shift displacement after application of the second saturation pulse, the second chemical shift displacement being different from the first chemical shift displacement.
