That is interesting and good to know. Thanks.
I am looking for a reference that provides validation metrics on the Van
Leemput (2010) method as implemented in Freesurfer. To your knowledge, is
there such a reference?
Best,
Joshua

Thanks Bruce and Eugenio,
Suppose I had two identical images of a subject, but in one image I
reduced the contrast of internal lamina while leaving the rest of the image
intact...just removing internal intensity differences, but leaving the
outer boundary contrast intact.
Would the images result
Dear Josh,
at this point, and given that the boundaries between these subfields
cannot really be seen in 1mm T1 scans, the algorithm assumes that all
the subfields other than fimbria and fissure share the same image
intensity properties. Therefore, using your own words:
"depend only on outward bo
Hi Josh
it depends on intensity differences if it can find them as well as
boundary/geometry.
cheers

I'm trying to understand Leemput's subfield algorithm better as implemented
in Freesurfer. Does the algorithm make use of intensity differences in the
internal hippocampal lamina from the subject's T1 image to warp meshes and
assign subfield probabilities? Or does it depend only on outward boundari
