Usefulness of a 3D turbo field echo (TFE) sequence with motion sensitized driven equilibrium (3D-MSDE-TFE) optimized for T1W carotid artery wall imaging was assessed in clinical practice. The sequence was compared with a conventional T1W 2D double inversion recovery turbo spin echo (2D-DIR-TSE) in five patients with soft plaque(s). The optimized sequence achieved T1 contrasts equivalent to those of the conventional one, while allowing larger spatial coverage without time penalty. Therefore, the optimized sequence may be appropriate for vessel wall screening.
