FIG 2. Phantom experiment to evaluate the effect of TE on 3D-CISS sequences. Water-filled polyethylene tube is coiled and placed on cubic water phantom.

A–C, 3D-CISS (12/6/1) (A), 3D-CISS (16/8/1) (B), and 3D-FASE (5000/241.6/1) (C) sequences. Bandlike susceptibility artifact is seen on A and B (arrows); however, it is slightly more prominent on B. There is no artifact on C (arrow). Note that the cubic water phantom signal is uniform in C. This experiment shows that shorter TE has some ability to reduce susceptibility artifacts on 3D-CISS studies, but 3D-FASE has far fewer susceptibility artifacts.
