In MRF, a single image is reconstructed from data collected from each short TR due to the non-repeatable magnetization history. The highly-undersampled single-shot imaging leads to high levels of noise and artifacts. In this study, an SR preparation module was introduced to MRF, enabling multi-shot MRF without a waiting time for magnetization recovery. The SR prepared multi-shot MRF can achieve similar or even better accuracy than the original single-shot IR prepared MRF with the same amount of data collected.
