ABSTRACT:
In order to prevent image quality degradation which occurs when a flow compensating pulse is applied in a pulse sequence according to the fast spin echo technique, a bipolar pulse constituted of gzfcf and gzmfcf (FIG. 5) is incorporated in the slice gradient before an inversion pulse applied immediately before the flow compensating pulse constituted of fcrdep and fcrrep incorporated in the read gradient in the pulse sequence, thereby imparting a phase shift equal to a non-linear phase shift due to the flow compensating pulse constituted of fcrdep and fcrrep.
