On the motion-robustness of TOWERS (T-One with Enhanced Robustness and Speed)

T1 mapping is beneficial in many respects. However, as with all other time-series acquisitions, motion is a significant threat. Our sequence is specifically designed to be robust to motion. GRAPPA calibration scans are performed multiple times for artifact-free image reconstruction and sub-voxel spin tracking is applied to correct for motion-related spin history distortions. The in vivo results show the promise of the approach.
