Hi,
We are setting up a new dti sequence on a 3T GE scanner. We are trying to match the recent recommendations concerning dti parameters and our limitation in terms of time for scanning pediatric patients (around 10 mins).
We ended-up with this set-up:
4 b=0 , 71 directions using (http://www.emmanuelcaruyer.com/q-space-sampling.php) on three shells: 1000, 2000 and 3000 b-value?
2 x 2 x 2 mm resolution?
12 or 32 channel head coils?
1 or 2 NEX?
B0 mapping to correct for the distorsions
Do you think it is reasonable to use this kind of acquisition or do we still need to stick to a more classical sequence?
Thanks for your answers.
