Comparison ChoCre/Cit measurement for PSF-Choice and standard phase encoding using the diagnostic-quality phantom. Error magnitude was computed as magnitude of the difference between Normal compartment measurements (N=20) and Cancer compartment measurements (N=58) and the true values of 0.70 and 1.43 respectively.
