A method for rapid acquisition of multiple scans of NMR sequences is presented. The method initially
applies two RF-pulses in combination with two magnetic field gradient pulses of opposite polarity, different
strength and different duration. The basic idea is to spoil any magnetization in any direction before by letting
the system recover to some degree of restoration of the thermal equilibrium magnetization. Thereafter any
pulse sequence can be applied, and the next scan may be run immediately after the end of the pulse
sequence. Thus one avoids the 5 times T1 delay between each scan. A set of PFG sequences are presented
that apply the spoiler recovery method for significant reduction in acquisition time, and the method has been
verified at 0.5 Tesla as well as at 11.7 Tesla.
