Improvement of MSDE for whole brain application was assessed in human volunteers study. The signal obtained by the improved MSDE sequence was compared with a conventional MSDE sequence at cerebrum area. The improved MSDE sequence achieved both better image homogeneity than when acquired with the conventional MSDE and the signal drop typical in conventional MSDE is absent. It is indicating that improved MSDE sequence is less sensitive to B0 and B1 inhomogeneity and EC effects. Therefore, it may be appropriate for whole brain application.
