We have developed a technique for simultaneously acquiring metabolite and water signals in chemical shift imaging. This technique consists of measurement shifting only the water signal on the image, and the data process separating the metabolite and water signals using the coil sensitivity difference. Since the superimposed metabolites and water signals received from multiple coils can be separated using the coil sensitivity difference, both signals can be acquired simultaneously without increasing the scan time. The results from phantom experiments showed that this technique is useful for the simultaneous acquisition of metabolite and water signals without increasing the scan time.
