Hi all, I'm having trouble determining whether or not to use our T2 images for the new pial refinement feature. *Most importantly, I'm wondering if our T2 image parameters are sufficient for the T2 pial refinement. The parameters of our T2 images are as follows:*
T2 TSE overlay with a voxel size of 1.1x1.1x3.5 mm (slice thickness). A couple other studies in our lab have a voxel size of 0.9x0.9x4.0 mm. Note that our MPRAGE voxel size is .9x.9x.9mm. In your release notes, it states we should uaround a 1x1x1mm (let me know if you need additional specifications such as geometry bandwidth etc): "T2/FLAIR used for pial surface refinement: if you have T2 or FLAIR scans ~1mm^3, then they can be used by the recon-all stream to refine the pial surfaces". I have experienced about 1/4 of our subjects with errors using the T2 pial flag. As a next step, if you think the parameters are acceptable, then I can send you some screen shots different errors that I have encountered wit these subjects. Best, Mike
