The challenging problem of MR living examination is how to obtain images with diagnostic image quality in a shorter scan time. The purpose of this study is to explore the value of 3D mDixon sequence using compressed SENSE (CS) technology in liver examination. Compared with free-breathing mDixon with 3D Vane sequence, breath-hold (BH) 3D mDixon SENSE factor 2 and BH 3D mDixon CS factor 2 sequence can effectively improve the signal-to-noise ratio, contrast-to-noise ratio of the image and the image quality, and significantly shorten the scanning time.
