Improving MEDIC/MERGE/M-ffe and GRE/FFE image quality |
Hi,
Sequences with multiple echoes are unfortunately sensitive to motion and flow artifacts, with the mFFE the echoes are still cumulated afterwards. The use of the head-neck coil provides better SNR. Important are good flow compensation, rest slab, try out foldover direction l/r vs. a/p. Shimming may help, synergy is sometimes better as clear, don't take too many slices, but maybe the signal loss is also a technical problem. Problems in the lung region are common. In short, we use 2D T2 TSE with continuous flow comp.
