Dear All,
I would like to ask you for some advice about
segmenting MRI from infants data.
In particular, these are my questions:
1. if I have two different templates related to
two different time points in the 1st year of life, and one of
this two is clearly a bad quality MRI image (even visible from
the T1 image), the other one is quite good.
While with the good one I can reconstruct and
segment the image perfectly, with the bad one the software is
of course missing lots of part during the reconstruction. Is
there the possibility to set up some lower threshold in the
‘recon-all' script to allow the segmentation to get more areas
considered, even with this bad quality image?
2. I know that the program register the volume with
the MNI305 atlas, that is supposed to work well with adults but
not with infants: I am actually trying to avoid in my whole
neuroimaging analyses (also with other softwares) to “stretch”
the infants brain to an adult one.
From the high quality MRI infants image that I was
able to segmented, the output seems to be fine, but my concern
was whether using as a reference an adult brain could affect the
results in my case, although the segmentation seems to be well
done.
I checked the FreeSurfer website but I couldn’t find
this information!
Any advice would be really appreciated!
Best Regards
Chiara
