Hello,

I have a set of archival data (so I was unfortunately not able to specify the acquisition sequences and include the recommended MPRAGE sequence).  I am asking which sequence (if any) would be most conducive to volumetric/regional analysis using FreeSurfer.  A Philips Achieva 3.0T was used for all acquisitions.  All patients all have a the following sequences:

FLAIR (TE 140ms, TR 10ms, Flip 90)

T2W_FFE (TE 16ms, TR 1.5s Flip 18)

Spin Echo (TE 16ms, TR 600ms Flip 90)

DUAL_TSE CLEAR (TE 13ms, TR 3.4s, Flip 90)

Would any of these be appropriate for segmentation and volumetric analysis?

Thank you very much.
