Multi-echo acquisition strategies have the advantage of simultaneous quantification of T1/T2* values in DCR MRI, and when combined with multiband strategies, could provide comparable spatiotemporal coverage as a single shot EPI dynamic scan. While there has been some work on SMS – SAGE acquisitions, this is potentially the first work that utilizes a SENSE reconstruction framework. We demonstrated that the CNR of MBSAGE with SENSE is similar to SAGE acquisitions, and that the dynamic CNR with respect to NAWM is on the order of or slightly higher than reported by some of the SMS-SAGE implementations in literature.
