In hybrid 3D FSE, the close proximity of pre-phaser and
the first refocus pulse makes the first refocus RF very
vulnerable to the short-term eddy current induced by the
pre-phaser. This causes image shadings in regions
distant from the magnet center. We propose to shift the
position of pre-phaser to post of the first refocus RF
to eliminate the image shading of hybrid 3D FSE
sequence.
