Hi All,
I would like to know if it is possible to use "eddy" on our data. Our DTI images were acquired with single-shot EPI (SENSE factor 2.5) on a 3T ‘Acheiva’ scanner (Philips, Best, the Netherlands). Two runs were collected in each subject, with 32 gradient directions (b = 800 s/mm3) and one b0 in each run. Sixty 2.2-mm axial slices were acquired for each volume, with 0.9 mm in-plane reconstructed resolution. We also acquired a non-EPI axially acquired T2-weighted image. Is it possible to average the two runs together and then run eddy? Can we still use eddy even though we do not have opposite phase encoding directions?
Thanks,
Colleen
