Multi-shot fast-spin-echo based PROPELLER (FSE-PROPELLER) combines the robustness to off-resonance and bulk motion and has been increasingly used in body imaging. However, FSE-PROPELLER methods require longer acquisition times compared with conventional FSE methods, especially in high resolution imaging with small FOV, since the oversampling is not confined to a single axis. Outer volume suppression alone can provide a modest reduction in scan time. In this work, we optimized the rotating outer volume suppression method and combined it with variable refocusing flip angles to further reduce scan time for high resolution T2W imaging.
