Abstract | This study presents a calibrationless parallel imaging (CPI) reconstruction for simultaneous multi-slice (SMS) PROPELLER MRI of the upper abdomen. With simultaneously excited slices having different blipped-CAIPI shifts, the inherent incoherency of SMS PROPELLER data enables CPI reconstruction via low rank matrix approximation. The proposed method was evaluated with both simulated phantom and acquired abdominal MR data. Compared to conventional split slice-GRAPPA, the proposed method jointly reconstructs all blades, providing significantly improved SNR and reduced artifact level. |
