Effects of Frequency Drift on the Quantification of Gamma-Aminobutyric Acid Using MEGA-PRESS
The MEGA-PRESS method is the most common method used to measure γ-aminobutyric acid (GABA) in the brain at 3T. It has been shown that the underestimation of the GABA signal due to B0 drift up to 1.22 Hz/min can be reduced by post-frequency alignment. In this study, we show that the underestimation o...
