A clinical CEST MR Fingerprinting pulse sequence is shown to simultaneously yield multiple accurate tissue parameter maps in a short scan time.

3: Reconstructed water relaxation (T1w, T2w), amide exchange rate (Ksw) and
volume fraction (fs) and semi-solid exchange rate (Kssw) and volume fractions
(fss) from an in vivo healthy subject imaged with the clinical CEST-MRF pulse
sequence.

A gaussian-shaped pulse train saturates the amide proton which then exchange
with the water protons. The reduction in the water signal is measured with an
EPI readout
