Figure 2. Effect of Respiration Correction in White Matter.

Figure 2

Mean z-spectra over all controls without correction (black), with the Jones method correction (green), and with our proposed correction (blue) demonstrate that features in the z-spectrum are confounded by physiological noise. The APT effect can be appreciated when the respiration correction is applied.
