Blipped-CAIPI imaging is widely used for fast imaging, which is one of the simultaneous multi-slice imaging methods. Conventional water-fat separation methods can be combined with the blipped-CAIPI technique. However, it results in the chemical-shift ghost artifact because fat signal on slightly shifted position is exited in the slice-selection process. This geometric error in slice-selection generates additional phase cycling, which causes the ghost artifacts on each slice’s fat image. In this abstract, a SENSE-based water-fat separation method is proposed, which considers the additional phase cycling on fat signal and obtains more accurate water-fat separated images.
