For single shot EPI, reduction in the number of phase encodes associated with parallel imaging has a small impact on scan time Typically 20-30% with a speedup factor of 2. Where time is critical, a better strategy for single shot imaging is to excite multiple slices simultaneously. However, this method suffers from high g-factor when transverse slice geometries are used because of unfavourable coil geometry We propose a new method to introduce an arbitrary shift between two simultaneously excited single shot EPI slices, allowing them to be separated by PPI with acceptable g-factors. We have demonstrated the method in vivo.
