CABIRIA is a method for the simultaneous quantification of T1 and T2 values of the myocardium. As other T1-quantification sequences, it relies on a bSSFP readout, and it is thus susceptible to off-resonance effects. In this work, we show an improvement over the CABIRIA method that reduces the TR and therefore increases the robustness towards field inhomogeneities. This method can potentially be extended to other quantification techniques.
