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.
