Fast single-shot three-dimensional k-space acquisition (free factor) with balanced turbo field-echo (bTFE) of the thoracic duct was performed. We compared the visualization of the thoracicdact among three sequences (free factor with bTFE, 3D turbo spin-echo sequence, and conventional bTFE). We divided the thoracic duct into three segments (upper, middle, and lower). Each segment was assessed using a five-point scale. We found good visualization of the thoracic duct using 3D free factor with bTFE.
