We propose a novel sequence for pre-contrast 2D myocardial T1 mapping during breath holds. Multiple blocks of two single-shot images are acquired for the generation of T1 maps. Different heart-rate independent T1 weighted contrasts are created by interleaving saturation and inversion pulses in the imaging blocks. This allows neglecting rest periods and enables the generation of heart rate independent T1 maps of high homogeneity in the absence of a contrast agent.
