FSE Triple Dixon (FTED) is a prototype sequence producing FSE T2-weighted images with superior fat suppression insensitive to field inhomogeneity. Each FSE readout gradient is replaced with three readout gradient pulses of alternating polarity. The respective echoes occur when fat and water are -180 degrees, 0 degrees, and +180 degrees relative to each other. After acquisition of base images a 2-point Dixon image reconstruction program automatically generates separate water-only and fat-only images for each slice. The efficiency of the FTED sequence allows for breath hold T2-weighted abdominal images without ASSET that demonstrates nearly perfect separation of fat and water signal.
