Abstract
An examination subject is subjected to radio-frequency pulses with a repetition time that is shorter than the spin lattice relaxation time of the nuclear spins under consideration. After each radio-frequency pulse, a plurality of echoes are acquired by a read-out gradient that multiply changes in polarity. Given this sequence, images can be acquired in fractions of a second despite long repetition times without special hardware being required.
