Spin and Gradient Echo (SAGE) imaging has been recently
developed in order to more robustly generate perfusion
parameters, as well as incorporate the ability to
determine tissue leakage in vivo. These properties make
it a very potent imaging sequence, however by acquiring
both spin and gradient echo images, the repetition time
is significantly increased. This necessitates acquiring
fewer slices with a longer repetition time than would be
necessary for either spin or gradient echo imaging
alone. This work presents increased slice coverage and
acceleration of SAGE using simultaneous multi-slice
imaging.
