Strategically Acquired Gradient Echo (STAGE) imaging is a novel and useful MR sequence which can provide seven different key modalities at the same time, T1w, PDw, SWI, T1 mapping, PD mapping, T2* mapping, and SWIM. However, the acquisition time is relatively long (about 8 minutes). The compressed sensing (CS) technique is now wildly applied for accelerating MR acquisition. This study aimed to evaluate the feasibility of CS accelerated STAGE technique, and find an optimal acceleration factor (AF). According to our preliminary results, the AF of 4 was recommended.
