We have developed a technique for sensitivity decomposition of water and metabolites combined with sensitivity encoding in order to acquire water and metabolites simultaneously and reduce aliased lipid. This technique consists of a measurement that shifts only water to the four corners on the image and a data process that separates each signal using the coil sensitivity difference. This technique reduces aliased lipid and acquires water and metabolites simultaneously without increasing the scan time. The results from phantom and healthy volunteer experiments showed that this technique is useful for acquiring water and metabolites simultaneously and reducing aliased lipid.
