Hi All,
Is the following T1 sequence suitable for surface generation?
"T1-weighted 3D SPGR (echo time 5 minimum; repetition time = 24 msec; flip
angle
= 30; field of view = 24 centimeters; slice thickness = 3 millimeters)
collected
in the axial plane."
It's that 3 mm slice thickness that most concerns me. The sequence was not
initially intended for surface reconstruction, but I've run a few volumes
through recon-all and they've turned out better than I had expected. We're
primarily using the output for automated ROI generation, but I'm wondering if
the cortical thickness and volume estimations from such an acquisition are
suitable for further analysis (i.e., group comparisons, correlations).
