Abstract
An SLP pulse is applied to an object to be imaged preceding one or more excitation pulses (a.sup.o or a) of a known magnetic resonance imaging technique. The SLP pulse tilts the nuclear magnetization away from the direction of B.sub.o, locks the magnetization with the rotating magnetic component and returns the magnetization back to the direction of B.sub.o. The known magnetic resonance imaging technique used with the SLP pulse includes applying at least one excitation pulse to generate transverse magnetization in the object. The excitation pulse causes the angle between the nuclear magnetization and B.sub.o to be less than 90.degree..
