1. A method for a magnetic resonance imaging (MRI) system, comprising:
acquiring k-space data with the MRI system according to a slice-ahead inversion sequence that jointly generates a contrast without inversion preparation and one or more inversion contrasts for a plurality of slices in a scan volume of a subject, wherein the k-space data comprises first k-space data of the contrast without inversion preparation acquired during one or more non-inversion repetitions and second k-space data of the one or more inversion contrasts acquired during one or more inversion repetitions, wherein a repetition time for each of the one or more non-inversion repetitions and one or more inversion repetitions is constant; and
reconstructing one or more images from the k-space data for each of the plurality of slices.
