T1-weighted fat-suppressed imaging of the pelvis with a dual-echo Dixon technique: initial clinical experience.

Compared with the standard T1-weighted fast spin-echo chemical shift fat-suppressed sequence, the three-dimensional dual-echo Dixon sequence yields superior-quality T1-weighted fat-suppressed MR images of the pelvis, enables better delineation of pathologic lesions, and requires one-twelfth the time necessary for standard imaging.
