We observed the chemical exchange saturation transfer (CEST) effects of water signal in left ventricular infarcted swine heart tissue on 7T clinical scanner. Significantly low CEST contrast was observed in infarcted region compared to non-infarcted region. Low CEST contrast in infarcted region may be due to combined effect from decreased concentration of creatine and low pH. Further characterization of this method on in-vivo animal model of myocardial infarction is in progress.
