We have applied a method that acquires simultaneously
the water and metabolite signals using multi-coil
sensitivities for proton chemical shift imaging (CSI)
thermometry. The method consists of measurement shifting
only the water signal on the image, and a data process
separating the water and metabolite signals using the
coil sensitivity difference. The results of a cooled
phantom experiments revealed that the method may be
useful for acquiring temperature map without increasing
scan time and contaminating the frequency modulation
sidebands caused by water signal.
