Re: [Freesurfer] quality T1 for new study

Hi Jelmer

the scan looks quite nice to me. Have you run it through recon-all? That 
is the best way to get an idea of how well it will work.


cheers

Dear Freesurfer experts,

I uploaded a .nii.gz file (which can be downloaded from 
'http://gate.nmr.mgh.harvard.edu/filedrop2/?p=7pbsgklemux'). I hope you
would be willing to comment on the quality of this scan for use with Freesurfer 
(you can find some parameters below; the scan
was acquired on a 3T Philips scanner). Running it through recon-all seems to 
give nice results, but then again, I am in a phase
of running pilots before the start of a new study, and I do not have much 
experience with Freesurfer results yet.

coil: 32 channel
Sequence: T1w_TFE_3D
TFE factor: 256
Acquisition time: 10:14
FoV FH256xAP256xRL160 mm
160 sagittal slices
fold-over direction AP
fat shift direction F
scan mode 3D
  
acquisition matrix 256 x 256
acquisition voxel size 1.00/1.00/1.00
reconstructed voxel size 1.00/1.00/1.00
TR shortest (=7.6ms)
TE shortest (=3.5ms)
RF: flip angle 8 degrees
Acceleration: no SENSE
inversion-prepared, inversion delay time: shortest

Cheers,

Hi Bruce,

Many thanks for your reply.

I did run it through recon-all and it seems to give nice results. Still, as I 
am just a beginner using Freesurfer, I would greatly appreciate it when you 
would have a look at the output which can be downloaded from 
'http://gate.nmr.mgh.harvard.edu/filedrop2/?p=69915f8pefn'.

Cheers,

Jelmer
