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 ;-)

External Email - Use Caution

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.

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

Nik
