A Simulation Framework to Investigate T1 Contamination on Diffusion Prepared RUFIS
Proceedings of the European Society for Magnetic Resonance in Medicine and Biology 32, Edinburgh, Scotland, UK October 2015 (bib)

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.
