An axial 2D spin-echo (SE) T2-weighted Fluid Attenuated Inversion Recovery (FLAIR) image: echo time (TE)/repetition time (TR)/inversion time (TI) = 140/11000/2800 ms, flip angle (FA) = 90[degrees], echo train length (ETL) = 50, acquisition matrix = 256 x 188, FOV = 250 [mm.
5 ms, FA = 90[degrees], ETL = 1, acquisition matrix = 260 x 209, FOV = 250 [mm.
71 ms), FA = 7[degrees], ETL = 7, acquisition matrix = 64 x 64, FOV = 220 [mm.
Such independence does not imply a lack of support for the rest of the acquisition matrix.
