DIFFUSION WEIGHTED MULTIPLE SPIN ECHO RARE SEQUENCE WITH PERIODICALLY AMPLITUDE-MODULATED CRUSHER GRADIENTS

摘要

A magnetic resonance imaging method which involves a pulse sequence for generating magnetic resonance signals and in which diffusion weighting is applied, for example, by way of a pair of gradient pulses which are separated by a 180° refocusing RF pulse. The magnetic resonance signals are generated as spin echo signals due to refocusing pulses. The refocusing pulses are flanked by compensation gradient pulses and the gradient strengths of the compensation gradient pulses are alternated according to a periodic pattern.
