Dear SPMers,
I would like to use the SPM5 unwarping tool to correct any distortions
on my spin-echo EPIs acquired at 3T.
Few questions:
1.) Are field map generation tool and unwarping algorithm usable on
spin-echo epi data (as SPM had been developed primarily for use with
BOLD acquisition)?
2.) Our scanner (3T Philips Achieva) acquires magnitude and phase images
based on gradient-echo non-EPI sequence. Can I use these images for
making the field map to correct spin-echo epi data, or would I have to
acquire se-epi data at 2 TEs?
All hints and advice will be extremely appreciated.
