Improving Image Quality Using the Pause Function Combination to PROPELLER Sequence in Brain MRI: a brain phantom study

Motivation: Finding ways to use the PROPELLER sequence as an even more the robustness method to motion. Goal(s): This study investigates whether repositioning the head after pausing during PROPELLER imaging, enhances image quality. Approach: This study investigated whether image quality improved with repositioning the head after a pause during PROPELLER method with a brain phantom and driver system. Results: We found that image quality improved at all rotational angles and that pausing multiple times was effective depending on the frequency of motion. Impact: Incorporating a pause function into the PROPELLER method is expected to be clinically applicable as a practical means to further improve the robustness of the PROPELLER method to motion.
