We compared the signal-to-noise ratio (SNR) of magnetic resonance spectroscopy (MRS) using two different sequences, namely, Spin ECho, full Intensity Acquired Localized spectroscopy (SPECIAL) and Point-REsolved SpectroScopy (PRESS). The SNR by SPECIAL was 15% higher than PRESS, which could be attributed to the difference in echo time.
