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). -SS
