Synopsis

Obtaining isolated effects in Chemical Exchange Saturation Transfer (CEST) MRI requires the correction for the influence of B0- and B1-inhomogeneities and the T1 relaxation time during post-processing. We present an extended approach for simultaneous mapping of B0, B1 and T1 using a CEST-like pulse sequence and a regularized neural network-based analysis that provides additional uncertainty estimations. We demonstrate the in vitro and in vivo applicability of the proposed approach, which is trained using simulated data and confirm its accordance with established reference methods.
