We investigated the usefulness of magnetic resonance spectroscopy (MRS) for water T1 relaxation time independent on the presence of fat in the liver phantom. Then,T1 relaxation time measurements were performed using inversion recovery-spin echo, modified look locker, variable flip angle, and MRS on a 3T-MRI system. T1 relaxation time measurement by the MRS water signal is less affected by the presence of fat and more accurate than the other methods. This technique does not use special research sequences and can be realized on clinical MRI scanner where MRS can be performed.
