Keywords: New Trajectories & Spatial Encoding Methods, New Trajectories & Spatial Encoding Methods, Spiral, FLAIR, LQWe describe our novel T2W 2D FLAIR sequence whose temporal and SNR efficiencies are maximized by (1) an efficient IR acquisition that minimizes sequence deadtime and (2) localized quadratic encoding which eliminates SNR-inefficiencies of multi-pass 2D acquisitions. These improvements allowed our FLAIR scan to shorten the scan time while achieving higher SNR than standard SE and 2D-TSE scans of identical/equivalent scan time.
