Presaturation Power Adjusted Pulsed CEST: A Method to Increase Independence of Target CEST Signals

<div>% change of the glutamate signal when the concentration is lowered in any one substance relative to the signal in the 4-high <i>z</i>-spectrum (asymmetry analysis). The signal is measured by the subtraction of 2.3 <i>µ</i>T/3 s from 5.5 <i>µ</i>T/3 s. The glutamate signal is reduced when its concentration is lowered (meshed column) but do not change much when the concentration of another substance is reduced.</div>
