CEST Peak Extraction method for multi peak fitting

MTR asymmetry is often used as a CEST parameter. However, it is influenced by other Z-spectrum peaks or high B1 of preparation RF pulse. In this study, CEST Peak Extraction method was defined and multi peak fitting was tried with a phantom. CEST peak could be fitted with Lorentzian function. B0 inhomogeneity, CEST peak width and peak area were calculated with raw egg white phantom. As a CEST parameter, CEST peak area was better than MTR asymmetry.
