Image acquisition of an mDixon sequence typically requires a breath hold to minimize respiratory motion artifact. Minimization the acquisition time of mDixon could be very useful in clinical daily routine. The purpose of the study is to explore the effect of the acceleration factor on the image quality of 3D mDIXON sequence for liver imaging using Compressed SENSE . And CS acceleration factor 4 can reduce the scanning time to 10s on the premise of ensuring the image quality, which is the best scheme for clinical 3D mDixon scanning of liver.
