In
this work, a bipolar acquisition with 3D-FSE-IDEAL is presented that reduces
total scan time by acquiring all three images required for IDEAL processing
in a single repetition. To eliminate
phase errors that arise from alternating polarities of the readout gradients,
a novel 2D phase correction method was implemented. High-resolution 3D T2-weighted
images with uniform fat-water separation are demonstrated in breast and knee
applications with less than 5-minute acquisition times.
