We propose magnetization preparation which combines saturation and inversion pulses, for improved Late Gadolinium enhancement imaging and T1 mapping in the presence of arrhythmia and heart rate variability. A saturation pulse right after the detection of the R-wave erases the magnetization history and is followed by an inversion time to enhance T1-weighted contrast.
