ABSTRACT:
An improved rapid acquisition relaxation enhanced (RARE) imaging method for measuring nuclear magnetic resonance in selected regions of a body is disclosed. The improved RARE imaging method includes introducing an evolution phase of time duration t.sub.2 between the excitation pulse and the first refocusing pulse of the multi-echo train. The evolution phase is introduced to influence the magnetization of the observed nuclei in such a fashion that the intensity and/or phase of the subsequent signals are influenced as a function of this evolution phase. This allows the effects of flow, motion, diffusion and local magnetic field inhomogenities to be measured.
