In vitro CEST imaging and Z-spectra of AM at different scanning parameters. a The chemical structure of AM; b, c CEST imaging of AM at different concentration and pH showed that the CEST effects of AM were concentration and pH-dependent; d, e Z-spectra of AM at different concentration and pH revealed that the clear CEST effect peaked at approximately 2.75 ppm; f, g Z-spectra of AM at different saturation power (μT) and saturation time (s) showed that the CEST effects were increased with the saturation power and time within a certain range. Colors bar represented the signal intensity
