Detection of glycogen and glucose in phantoms by using glycoCEST. (A and B) Z spectra and MTRasym plots for samples of glycogen (A) and glucose (B) in PBS buffer at 37°C (pH 7.4). Notice the visibility of multiple OH resonances in the glucose sample. (C) When plotting the MTRasym integral as a function of concentration, linear dependence is found at a lower concentration but not at higher values (see text).
