External Email - Use Caution
A few more questions regarding the use of a FLAIR image.
1) If one is using the hires option on T1 images acquired with sub-millimeter spatial resolution then, to get the best results with the FLAIR option, is matching spatial resolution required for the FLAIR sequence?
2) In a post some time ago (https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg51413.html) you said "V6 was not meant for T2/FLAIR and we didn't test it extensively. We have been optimizing things in the past week for T2/FLAIR and I expect 6.1 will be better for them". Are the changes you were referring to incorporated in the current development version?
3) Are then any plans to use the FLAIR for multi-modal segmentation in order to refine the segmentation of the Pallidium and Putamen, and to possibly segment structures such as the substantia nigra and red nucleus?
Thanks,
Richard

I am not too sure if I have asked you this question before. I know the use of a flair or T2 helps with dealing with the dura. I was wondering if there are other benefits??
