Efficient and accurate baseline T1 and B1 quantification is a pre-requisite for standardized and clinical Dynamic Contrast-Enhanced MRI (DCE-MRI). This study investigates a new approach called Multiple TR B1/T1 Mapping (MTM), capable of fast, simultaneous B1 and T1 mapping. In this work, MTM is analysed with respect to its T1 mapping performance in comparison with an inversion recovery reference sequence and in due consideration of the limited time allowed in a clinical set-up. In calibrated phantom measurements, MTM T1 mapping was found to be more accurate than IR-TSE, inter alia due to its intrinsic B1 correction mechanism.
