Hi SPMrs!
We have some stroke data that we want to analyse. For the
normalization, we want to use Unified Segmentation with CFM, as these
patients have big lesions. We have scanned both a T1-weigthed (1x1x1
mm3) and a FLAIR (0.5x0.5x1 mm3). The thing is that, in order to
identify the lesions, depicting them on the FLAIR is much easier.
My question is, would it be OK to depict the lesions on the FLAIR and
use this same FLAIR image as an input to Unified Segmentation to
derive the normalization parameters?
Or would it be better to create the lesion masks on the FLAIR,
corregister and reslice these masks onto the T1 weighted space and
then use the T1 with Unified Segmentation?I am thinking on this, as if
I am not mistaken, SPM8 has the ICBM 452 as a template, which is an
average of T1s and not FLAIRS.
Thanks a lot!!
