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
