Fast Field Cycling MRI offers the possibility to
explore new contrasts generated from NMR dispersion (NMRD) profiles of tissue
or contrast agents. Here, it is shown that dreMR contrast can be generated and
optimized in fast low flip angle sequences extending the range of sequences
that can be used with this new degree of freedom. The expression of a
generalized Ernst angle maximizing signal with dreMR pulses is derived as well
as the angle maximizing the dispersive contrast.
