[Freesurfer] [Philips 3T MRI protocol Recommendation for FreeSurfer]

[김정식]

Dear FS team, we are using Philips Achieva 3T scanner for acquiring our MRI data. Our T1-weighted MRI protocol as follows: - 3D T1 TFE coronal - 0.5x0.5x1.0 voxel resolution - FOV 240x240 mm - TR/TE = 9.8/4.6 ms - Spacing between slices: 0.5 mm - NSA (=NEX=ACQ) = 1 - Bandwidth = 142 Hz/Px In our most cases, we failed to good output for constructing cortical surfaces. Most problems were from including dura mater portions into pial surfaces. In the FreeSurfer wiki, I found the optimized MRI protocol using "3.0T Siemens 3D T1 MPRAGE" for FreeSurfer. I would like know what are the recommended parameters for Philips 3T machine to acquire good quality of cortical surfaces. I am wondering if you could give an idea of a sequence of Philips working well in FreeSurfer.   Thank you very much. Jeongsik Kim
