| Zusammenfassung | One of the bottlenecks in Chemical Exchange Saturation Transfers /CEST) MRI is its susceptibility to magnetic field inhomogeneities and dependecy on T1 relaxation times. To enable efficient correction for these parameters, we propose a new method for simultaneous quantitative mapping of B0, B1 and T1 using a simple CEST sequence with a modified preparation block. For the analysis, we developed a neutral network that provides an additionell uncertainty estimation for each parameter. First results on phantom simulations demonstrate the feasibility of this approach as well as its applicability for the correction of CEST-MRI data. |
