This study aims to employ random phase encoding in MR Chemical Shift Imaging (CSI) to reduce measurement time without significantly sacrificing image quality. CSI is a good candidate because the 2D-CSI sequence has the freedom to independently set the two directions of phase encoding. Simulations show efficient suppression of intervoxel contamination at undersampling factors up to 65% while maintaining image quality at undersampling factors up to 50%. This results show that CSI can significantly reduce measurement time.
