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.
