Dear Jeffrey,
I will email you a copy of an internal report we generated on the
asymmetric spin echo study. If anyone else on the list would like a copy
please email me a request.
We have several papers out on activation in the amygdala using a short
TE and relatively thin slices (4mm skip 1). As for orbital, we do acquire
nice lateral orbital cortex, but do not get good signal from medial orbital
cortex. After consulting with a number of physicists, we decided to scrap
using asymmetric spin echo and just used the short TE (40ms) and 4mm axial
slices.
Hope this helps,
Best regards,
Kent
