DOI: 10.1002/mrm.29408
Abstract: Chemical exchange saturation transfer (CEST) imaging measurement depends not only on the labile proton concentration and pH‐dependent exchange rate but also on experimental conditions, including the relaxation delay and radiofrequency (RF) saturation time. Our study… read more here.
