Hi,
Freesurfer reported the following hippocampal volumes for a subject
volumeInVoxels: right_CA1: 2652.3 right_CA2_3: 7245.11 right_CA4_DG: 3967.28 right_fimbria: 423.555 right_hippocampal_fissure: 191.897 right_presubiculum: 3598.99 right_subiculum: 4868.1 Right-Hippocampus: 3258.77
I have two questions about it
1. I don’t understand why the right_subiculum volume is more than the Right-Hippocampus volume. 2. Since the voxel size for the volumes is 0.5^mm, do we have to divide these volumes by 8 to convert them to voxel size 1^mm so that we can do direct comparison with other freesurfer stats volume (for example the volumes in rh.aparc.stats)?
Thanks --Mohammad Zia
