SucCEST map of sucralose. a sucCEST map obtained from 10 mM sucralose phantom at 37 °C shows ~11% contrast. b The graph shows linear increase in the sucCEST contrast with increase in sucralose concentration. c, d Z-Spectra and MTRasym curves from different pHs show higher sucCEST contrast with decrease in the pH. e The graph shows a slope of 14.5% change in sucCEST per unit drop in the pH
