We propose a method that combines the sensitivity decomposition method with the sensitivity encoding method for simultaneously acquiring water and metabolites signals to reduce the scan time. This method consists of a measurement that shifts only the water signal on an image and undersamples in k-space, and a data process that separates each signal by using the coil sensitivities. The results of experiments with a healthy volunteer showed that the proposed method reduced the scan time to one-fourth of the fully sampled CSI, to which non-water-suppressed measurement was added.
