Separation of slices simultaneously acquired in multi-band EPI is problematic when the N/2 ghost needs different correction parameters for different slices. We present a straightforward manner of combining the slice-dependent ghost correction with multiband SENSE. The method inverts the sensitivity encoding equations for separately reconstructed even- and odd-echo data. It achieves a significant complexity reduction compared to the previously proposed k-space-based approach.
