so no T1-weighted scans at all? If not, we probably won't be able to help you

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.
