ABSTRACT:
A method and an apparatus for a locally resolved investigation of a speci, wherein the specimen is exposed to a constant magnetic field and a variable combination of three gradient magnetic fields directed substantially perpendicularly to each other and to a sequence of high-frequency (RF) pulses which contains three successive pulses with flip angles not equal to .vertline.m Pi.vertline., and signals corresponding to a magnetic resonance of spin moments, in particular nuclear spin moments in said specimen are detected. The interval (tau) between the first and the second pulse is greater than T.sub.2eff and smaller than 5T.sub.2, and that the interval (T-tau) between the second and the third pulse is greater than T.sub.2eff and smaller than 5T.sub.1, wherein
