Hi All,
I have 1x1x3 cubic mm T2 and 1x1x1 cubic mm FLAIR, in addition to 1x1x1 cubic mm MPRAGE. Can you please let me know whether I should use only T1 or should I use one of the additional seq. for hippocampal subfield segmentation ?
cheers

I think it’s an empirical question. I would try both on a bunch of subjects and then decide. But my gut feeling is that T1+T2 will do best. Cheers, /Eugenio

Eugenio, You said the T1+T2 would be best. The T2 Nik has is not 1mm isotropic but the Flair is. Is a FLAIR in general not benifisiol

Sorry sent that last email by accident. Here is the finished version
Eugenio, You said the T1+T2 would be best. The T2 Nik has is not 1mm isotropic but the Flair is. Is a FLAIR in general not beneficial. Can you please elaborate.

1x1x3 is a no-no. The 1x1x1 FLAIR may or may not help; it’s hard to tell (especially without seeing the images!). But I would try both T1 and T1+FLAIR, and see what happens ;-)
