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.
