Rotating Ultra-fast Imaging Sequence (RUFIS) is a radial acquisition scheme that allows fast and robust acquisition for magnetization prepared sequences. However, T1-recovery during readout is a common issue for magnetization prepared sequences and introduces unwanted bias. Previous studies reported imaging parameters optimization, RF phase cycling or k-space filtering to reduce T1-contamination. In this study, we established a simulation framework to investigate the effect of imaging parameters and RF-cycling scheme on reducing T1-contamination for diffusion prepared RUFIS.     «
