Hi,
I am wondering how can I get the volume of hippocampus within a certain range? Given that the most anterior and posterior part of hippocampus may be more susceptible to errors because of other structures like amygdala and fornix, so I am wondering if the measurement would be more reliable if the most anterior and posterior parts of it are excluded. For example, calculate the volume of hippocampus without the most anterior and posterior 4 slices?
I guess I could calculate manually, by summing the product of area of hippocampus on every specific slice and the distance between slices. But where can I get the information about the area on every slice? And what is the distance between the two slices (if for the coronal view)? Does it depend on the original DICOM files, or does Freesurfer do some re-slicing during the reconstruction?
Thank you very much! Best, QJ
