The non-CPMG sequence permits to acquire MR signal in the Fast Spin Echo mode even when the CPMG (Carr Purcell Meiboom Gill) phase conditions cannot be fulfilled. It consists in a quadratic phase modulation of the refocusing pulses train, preceded by a suitable preparation period. It turns out that this sequence of RF pulses can be readily inversed permitting a perfect Driven Equilibrium scheme to be applied.
