MRI sequences and associated image reconstruction software to generate parametric maps sensitive to myelin content. The proposed sequences have been optimized for MRI acquisitions operating at 1.5 T and 3 T (work in progress at 7T) for human explorations. Preparation of the magnetization is performed using RF pulses concentrated in time (low duty cycle) to significantly enhance the resulting signal; this preparation can be combined with a pseudo-stationary gradient echo readout (GRE or SPGR), or a fast gradient echo readout (RAGE or TFL).
